ui: chore - upgrade ember and friends (#14518)
* v3.20.2...v3.24.0

* Fix handle undefined outlet in route component

* Don't use template helper for optional modal.open

Using the optional-helper here will trigger a computation
in the same runloop error. This is because we are setting
the `modal`-property when the `<Ref>` component gets
rendered which will update the `this.modal`-property which
will then recompute the `optional`-helper leading to this
error.

Instead we will create an action that will call the `open`-method
on the modal when it is defined. This gets rid of the double
computation error as we will not access the modal property
twice in the same runloop when `modal` is getting set.

* Fix - fn needs to be passed function tab-nav

We create functions in the component file instead
so that fn-helper stops complaining about the
need to pass a function.

* Update ember-exam to 6.1 version

"Makes it compatible" with ember-qunit v5

* scheduleOnce setMaxHeight paged-collection

We need to schedule to get around double-computation error.

* Fix - model.data is removed from ember-data

This has been private API all along - we need to
work around the removal.

Reference: https://github.com/emberjs/data/pull/7338/files#diff-9a8746fc5c86fd57e6122f00fef3155f76f0f3003a24b53fb7c4621d95dcd9bfL1310

* Fix `propContains` instead of `deepEqual` policy

Recent model.data works differently than iterating attributes.
We use `propContains` instead of `deepEqual`. We are only
interested in the properties we assert against and match
the previous behavior with this change.

* Fix `propContains` instead of `deepEqual` token

* Better handling single-records repo test-helper

`model.data` has been removed we need to handle proxies and
model instances differently.

* Fix remaining repository tests with propContains

We don't want to match entire objects - we don't care
about properties we haven't defined in the assertion.

* Don't use template helper for optional modal.open

Using a template helper will give us a recomputation error -
we work around it by creating an explicit action on
the component instead.

* Await `I $verb the $pageObject object` step

* Fix no more customization ember-can

No need to customize, the helper handles destruction
fine on its own.

* Fix - don't pass `optional` functions to fn

We will declare the functions on the component instead.
This gives us the same behavior but no error from
`fn`, which expects a function to be passed.

* Fix - handle `undefined` state on validate modifier

StateChart can yield out an undefined `state` we need
to handle that in the validate modifier

* Fix linting errors tests directory

* Warn / turn off new ember linting issues

We will tackle them one by one and don't want to
autofix issues that could be dangerous to auto-fix.

* Auto-fix linting issues

* More linting configuration

* Fix remaining linting issues

* Fix linting issues new files after rebase

* ui: Remove ember-cli-uglify config now we are using terser (#14574)

# StateMachine

```hbs
<StateMachine
  @chart={{xstateStateChartObject}}
  as |fsm|>
</StateMachine>
```

`<StateMachine />` is a renderless component that eases rendering of different states
from within templates using XState State Machine and Statechart objects.

**Please note**: This component is currently a gradual replacement for
StateChart, which has a less ergonmic interface. Guard and Action component are
currently omitted due to a preference to use entries to define those instead of
components (which is WIP)

### Arguments

| Argument/Attribute | Type | Default | Description |
| --- | --- | --- | --- |
| `chart` | `object` |  | An xstate statechart/state machine object |
| `initial` | `String` | The initial value of the state chart itself | The initial state of the machine/chart (defaults to whatever is defined on the object itself) |

The component currently yields 1 contextual components:

- `<fsm.State />`: Used for rendering matching certain states ([also see State Component](../state/README.mdx))

and 2 further objects:

- `fsm.dispatch`: An action to dispatch an xstate event
- `fsm.state`: The state object itself for usage in the `state-matches` helper

### Example

```hbs
<StateMachine
  @chart={{xstateStateChartObject}}
  as |fsm|>
    <fsm.State @matches="idle">
      Currently Idle
    </fsm.State>
    <fsm.State @matches="loading">
      Currently Loading
    </fsm.State>
    <fsm.State @matches={{array 'loading' 'idle'}}>
      Idle and loading
      <button disabled={{state-matches fsm.state "loading"}} onclick={{action fsm.dispatch "START"}}>Load</button>
    </fsm.State>
</StateMachine>
```
