Adding this in `dev-cmd/ruby.rb` allows us to suppress warnings like:
```
/home/linuxbrew/.linuxbrew/Homebrew/Library/Homebrew/language/python.rb:8: warning: Insecure world writable dir /home/linuxbrew/.linuxbrew/Homebrew/Library/Homebrew/shims/scm in PATH, mode 040777
```
It's not sufficient to do this merely on `brew upgrade` because
`brew install` and `brew reinstall` can also result in formulae being
upgraded.
This requires moving logic from `cmd/upgrade.rb` to `upgrade.rb`. To
save you searching the diff the changes that resulted from doing that:
- Query the installed formulae from class state in `FormulaInstaller`
rather than the (incomplete) list that we passed into it.
- Don't output the "Checking dependents" message. It was there for
systems and configurations where this is slow but for most users
and most installations this will be a (annoying, noisy) no-op.
Fixes https://github.com/Homebrew/brew/issues/7860
- Make `brew extract` strip out bottle blocks
- Make `brew extract` output the path in a readable fashion
- Warn about building from source before fetching (not installing)
- If fetching a bottle fails, refetch and build from source.
- Trying to test out a user-submitted `brew bump-formula-pr` for
`app-engine-java` gave an error locally that [hasn't shown up on
CI](https://github.com/Homebrew/homebrew-core/pull/55798/checks?check_run_id=740165542),
oddly.
```
