* add EIP-7044 support to keymanager API
When trying to sign `VoluntaryExit` via keymanager API, the logic is not
yet aware of EIP-7044 (part of Deneb). This patch adds missing EIP-7044
support to the keymanager API as well.
As part of this, the VC needs to become aware about:
- `CAPELLA_FORK_VERSION`: To correctly form the EIP-7044 signing domain.
The fork schedule does not indicate which of the results, if any,
corresponds to Capella.
- `CAPELLA_FORK_EPOCH`: To detect whether Capella was scheduled.
If a BN does not have it in its config while other BNs have it,
this leads to a log if Capella has not activated yet, or marks the BN
as incompatible if Capella already activated.
- `DENEB_FORK_EPOCH`: To check whether EIP-7044 logic should be used.
Related PRs:
- #5120 added support for processing EIP-7044 `VoluntaryExit` messages
as part of the state transition functions (tested by EF spec tests).
- #5953 synced the support from #5120 to gossip validation.
- #5954 added support to the `nimbus_beacon_node deposits exit` command.
- #5956 contains an alternative generic version of `VCForkConfig`.

In #5120, the `nimbus_beacon_node deposits exit` command was updated for
compatibility with EIP-7044, which forces signatures to be made using
`CAPELLA_FORK_VERSION` regardless of the `VoluntaryExit`'s `epoch` after
Deneb is activated.
This update had a regression, as an older mechanism was used to fetch
`RuntimeConfig`, resulting in an encoding issue (#5362). This was then
fixed in #5370, restoring general `deposits exit` functionality.
However, the logic from #5120 has another flaw, as it uses an incorrect
fork version based on the pre-Deneb logic even after Deneb and EIP-7044
are activated. Fix this now, so that `deposits exit` continues to work
correctly after Deneb activates.
Other fixes:
* Fix bit rot in the `make prater-dev-deposit` target.
* Correct content-type in the responses of the Nimbus signing node
* Invalid JSON payload was being sent in the web3signer requests
Some upstream repos still need fixes, but this gets us close enough that
style hints can be enabled by default.
In general, "canonical" spellings are preferred even if they violate
nep-1 - this applies in particular to spec-related stuff like
`genesis_validators_root` which appears throughout the codebase.
