"curl" is the binary, while "cURL" is the umbrella project.

We use only one sha type right now.

The current casks audit is very noisy in the no-op case (i.e. no errors)
https://github.com/Homebrew/brew/pull/10234/checks?check_run_id=1655630568#step:15:7

This means when there are errors and you're querying all casks it's
pretty hard to quickly identify the problems.

This commit silences the `passing`, `warning` and header/summary output
when you're querying all casks (rather than a specific cask or tap).

This is more consistent with `brew audit` for formulae which is silent
unless there are audit failures.

If the tap of the conflicted cask is not installed, we should just skip it.
This matches the behavior of formula installation.

Without this, running `brew install dropbox` would result to install
the `homebrew/cask-versions` tap.

Fixes #9125.

More deprecations, disabling and removal for Homebrew 2.7.0.

This probably has to wait until 2.7.0 now and will require a bunch of
formula changes/deprecations but we should probably start moving in this
direction given we're not installing any of these on our CI any more.
