Update reaction types (#1068)

Resolves #1054
Added "ROCKET" and "EYES" to the list of reaction types.
Added "ROCKET" as a valid cred signal, kept "EYES" invisible.

My approach was to use `git git grep THUMBS_UP '*.js'`
 and `git grep ThumbsUp '*.js'` to find all the relevant files,
as suggested in #1054

**Test Plan**

1) Inspecting Sourcecred/Mission's UI:
[#13] contains: GOT 🚀 FROM 1 user
@BrianLitwin contains: REACTED 🚀 TO 1 issue
@BrianLitwin contains: REACTED 🚀 TO #13

2) Yarn Test passes

3) `github/edges.test` includes a snapshot test to verify
that we can create an edge using ROCKET

4) @wchargin also noted that:

```sh
diff -u <(git grep -c 'THUMBS_UP' '*.js') <(git grep -c 'ROCKET' '*.js')
diff -u <(git grep -c 'ThumbsUp' '*.js') <(git grep -c 'Rocket' '*.js')
```

passes.

`graphql/mirror.test` now includes "ROCKET" and "EYES" in the  example
GithubSchema, but their inclusion has no effect
on any tests.
