Improve @-versioned formulae linking.

Keg.for: handle non-existent path.

Unify and use Git username/email/GPG handling.

Fixes #9017

`--formula` is now required for `brew list`, otherwise an error message
is printed.

Fixes #9017

Otherwise `path.realpath` will raise `Errno::ENOENT` rather than the
expected `NotAKegError`.

Fixes https://github.com/Homebrew/brew/issues/9015

We're using essentially the same logic to setup Git for committing in
multiple places but the way we're doing so is inconsistent. Moved to
using two shared utility methods and use them consistently.

also add formatting to download URLs

This more closely matches requirements' display in the DSL.

Revert "Improve @-versioned formulae linking."

Improve @-versioned formulae linking.

The way we currently handle @-versioned formulae linking is pretty
labourius:
- it requires extensive use of `link_overwrite` to avoid the `link`
  stage failing on certain install/upgrade scenarios
- we teach people to use `brew link --force` whenever they wish to
  link a versioned formulae when it's pretty obvious what's expected
  in that situation

Instead, let's:
- automatically unlink other versioned formulae when linking a
  versioned formula (either through `brew link` or `install`/`upgrade`
  /`reinstall`)
- notify the user what we've done (with the same messaging as if
  they had run `brew link` manually)

spec_helper: fix Timeout::Error/SystemExit handling.

build(deps): bump sorbet-runtime from 0.5.5973 to 0.5.5981 in /Library/Homebrew

These need to be manually caught and set otherwise they will not be
retried by `rspec-retry`. This is particularly annoying and a cause of
CI failures when tests timeout but are not retried.
