docs/Maintainer-Guidelines: Reflect `brew mirror` now being automatic

- Thanks to #7709, we've saved some maintainer time from doing this
  manually.
- To check that it's working, search for "Mirrored <formula_name>" in the CI
  log output for the publish bottles action for relevant formulae like
  ImageMagick in the future.

bintray: automatically run brew mirror if needed

Resolve errors reported by Sorbet

Sorbet was reporting errors (error code: 4010) on the auto-generated tapioca RBI files.
Since sorbet-typed has a good enough RBI for json hence we can exclude json from tapioca generation using the --exclude flag.

Initialize Tapioca

The behavior of some programs (e.g., emacs) differs depending on
whether INFOPATH is terminated in a colon or not. For example, the
info viewer built into emacs has a default list of places from which
it will draw info files, and it will only check this if either (a)
INFOPATH is unset, or (b) INFOPATH ends in a colon.

Currently brew shellenv prepends to the existing $INFOPATH and will
separate with a colon if $INFOPATH already exists, but if it does not
it will not terminate in a colon. As a result, info
pages (like emacs and elisp) are missing from the info viewer.

The existing brew shellenv logic used a parameter expansion trick to
include a colon only if it was prepending to an extant INFOPATH, but
because we want brew's contribution to the INFOPATH to always end in a
colon (whether there's an existing INFOPATH or not), we don't have to
use the parameter expansion trick

This commit only changes behavior for "other" shells (i.e., not fish,
csh, or tcsh) since I don't know how to append a colon to variables in
these shells.

audit: Supress pre-release audits for known pre-release formulae

- This safelists one formula that has only ever shipped pre-releases,
  from before we had the GitHub pre-release audit. So it won't fail CI
  and cause maintainers more work to determine if it's always been that
  way, or if it's new. Then, we don't have to keep comments at the top
  of files to say so for the next contributors.
- We should check this list from time to time to make sure that the
  formulae here have graduated to actual releases and we can remove
  them.

tap-new: restrict new tap names.

Don't want to restrict this for all taps otherwise existing ones may
explode.
