Improve ZSH completions handling

Work around BOM `find` bug.

- Only display the completions caveats from the current shell (assuming
  it's one of Bash, ZSH or Fish)
- If the completions location isn't in the ZSH `FPATH` then link to the
  documentation explaining how to do so.

Fixes https://github.com/Homebrew/brew/issues/8984

Don't output backtrace in `Formulary`.

docs: explain why upgrade upgrades unrelated stuff

formula_auditor: add cairomm@1.14 to allowlist

Properly handle outdated cURL

dev-cmd/unbottled: add new command.

Add a new command to list formulae that aren't bottled for a given OS.

Try retrying BOM `find` command.

Add types for `Formula`.

Deprecation fixes

fix: launchctl list can return empty id

pr-pull: fix empty workflow check

- `brew uninstall --zap` replaces `brew cask zap`
- clarify how `--json` should behave

Fixes https://github.com/Homebrew/brew/issues/9296

workflow_run is an array, which first element is the json
returned by the github API. We need to check that first element
if we want to know if the workflow exists.

cmd/list: --formula is no longer a default.

Handle macOS versions >= 11.1 correctly.

This behaviour is disabled.

Deprecate remaining cask commands.
