Allows you to avoid the `Keg::ConflictError` recommending that you invoke `brew link --overwrite` in scenarios when you know that that's how you'd proceed anyway.
There's a few bits of functionality that Homebrew has changed over the
years, makes sense as a sensible default but some people find really

Likely, the right thing to do is simply install the arm64 version of the
requested package. This can be accomplished using: arch -arm64 brew ...

- Output `brew doctor` and `brew install` messages noting this configuration is (currently) unsupported and encourage use of Rosetta instead
- Output Rosetta 2 usage in `brew config` on ARM (whether in Rosetta 2 or not)
- Check the architecture of (newly installed) dependencies and ensure they are using the correct architecture.
- Don't allow installing macOS Intel Homebrew in macOS ARM Homebrew default prefix (and vice versa
- Actually write out the architecture of dependencies to the tab rather than generating and throwing them away
- Set and document the expected default prefix for macOS Intel Homebrew, macOS ARM Homebrew (`/opt/homebrew`) and Homebrew on Linux
While we're here:
- Don't say Big Sur is a prerelease version but still make it clear we
don't support it (yet).
- Don't reference non-existent IRC channel
- This also required auto-fixes for Layout/EmptyLinesAroundBlockBody and
Layout/InconsistentIndentation once the auto-fixer had got rid of the
"redundant begin"s.
