The change in !11728 would cause an arbitrary project to be chosen to test
system hooks, and it's likely that the project would not have any commits or
relevant commits to test the hook. This would prevent admins from verifying
that the hook fired. Instead of trying to create a representative hook
dynamically, just send static data to guarantee the hook will actually be
tested.

The ACE editor JavaScript may not be loaded when the spec

Closes #37073

We perform a ton of expensive setup in this spec, via both `before` and
`let!`. When we use `skip` inside an `it` block, rather than skipping
the block entirely via `xit`, we still perform this expensive setup,
only to do absolutely nothing with it, resulting in wasted time.
Minutes, in this case.

Further, these specs have been sitting in our test suite for about seven
months now, so the likelihood of them being addressed soon seems low.
