- I was going through the `sorbet/files.yaml` moving various things to
  `true`, playing around locally, and happened upon some files that it
  was tracking that had been deleted.
- We want to do some automation of new files, but I'm not sure we'd ever
  considered the possibility of code being removed. :-D
- This adds a `--prune-files-list` switch and updates the Tapioca GitHub
  Actions workflow to use it. Any changes to the `sorbet/files.yaml`
  file will be committed as part of the scheduled Tapioca update job.

It blocks uploading to GitHub Releases where Bintray credentials are not needed.
Also those checks are already performed in `bintray.rb`.

This allows reducing the volume of `brew update` output by only
outputting the changes to formulae that you have installed.

Also add `--commit` to a create commit without opening a pull request

Do the usual "disable deprecations" and "uncomment pending deprecations"
dance and delete/deprecate/disable relevant/related code.

This PR adds a new `brew typecheck` developer command which checks for
typechecking errors in the current code with Sorbet.

- Add `--stackprof` to allow using stackprof
- Use the latest version of `ruby-prof`
- Automatically open the generated HTML output

also fix typo in `--root-url` option

These were all made `--formulae` and `--casks` for consistency but that
doesn't behave as expected because they have special behaviours in
`args`. Instead, use the singular form everywhere.

This allows auditing a single tap (so is useful for `test-bot`).

- Ensure the usage documentation always mentions casks when appropriate
- Use --formulae or --casks consistently
- Provide --formulae and --casks switches to upgrade
- Mark more switches as conflicting

This should allow better handling flaky tests.

This should help with cases like
https://github.com/Homebrew/homebrew-bundle/issues/751
and is good practise in general.

Also, document the `brew update --preinstall` flag that is being used
here so others can run it manually e.g. as part of CI if needed.
