Add these and correctly pass through a string to
`GitHub::Actions.puts_annotation_if_env_set`.
Also, fix some call sites to not rely on the `void` return.
We already do this for deprecations but these may make warnings
and errors from Homebrew easier to spot in GitHub Actions logs.
While we're here, cleanup other cases that should have used
`GitHub::Actions::Annotation` but didn't and provide some helpers and
tweaks there necessary for our use case here.
This caused formulae with uses from macos bounds to not load correctly
because they tried to modify a frozen hash. It wasn't obvious from
the tests because I didn't replicate the real world JSON parsing
conditions closely enough. I also had to modify `Cachable#clear_cache`
so that it can clear frozen hashes.
Error:
```
Error: can't modify frozen Hash: {"since"=>"catalina"}

This leads to undesired linkage with LLVM's `libunwind` (because it
shadows the system's `libunwind`).
See, for example, Homebrew/homebrew-core#169354.
This should make these messages, particular warnings, more obvious to
GitHub Actions users.
There's an argument perhaps we should do this more broadly for all
warning/error messages but: this feels like a good start.
