The `curl --head --request GET` causes a full download to happen on
`curl` from 8.7.0 to 8.9.1[^1] which causes poor UX due to slow
Cask downloads that can take almost twice as long as they should.

- Part of trying to reduce the number of `Excludes:` we have in our
RuboCop configs.
- The fixes here all seemed reasonable, with some minimal tweaks for
line length and less floatiness. Apart from `test/dev-cmd/bottle_spec.rb`
where RuboCop wanted to do some ridiculously floaty indentation and there
wasn't an obvious alternative place to break the lines, so I opted for
in-line disables instead.
add support for credentials usage in combination with other mirroring
features. previously `HOMEBREW_DOCKER_REGISTRY_TOKEN` and
`HOMEBREW_DOCKER_REGISTRY_BASIC_AUTH_TOKEN` where only used in combination
with `HOMEBREW_ARTIFACT_DOMAIN` which affects *all* curl download strategies.
`HOMEBREW_BOTTLE_DOMAIN` is only used for bottle artifacts, whose mirror might
also require credentials.
this change removes the requirement of using `HOMEBREW_ARTIFACT_DOMAIN`.
