The other syntax for setting `ENV` was added in #9013,
but this form remained undocumented.

Fixes #8648.

Refactor `brew typecheck` and upgrade `typed` sigils.

bottle merge: add support for linux cellar

livecheck: refactor url preprocessing

Improve ZSH completions handling

Work around BOM `find` bug.

- Only display the completions caveats from the current shell (assuming
  it's one of Bash, ZSH or Fish)
- If the completions location isn't in the ZSH `FPATH` then link to the
  documentation explaining how to do so.

Fixes https://github.com/Homebrew/brew/issues/8984

- support both `github.com/downloads/<owner>/<repo>` and
  `github.s3.amazonaws.com/<owner>/<repo>` URL patterns
- support self-hosted GitLab installations (with project groups)
- support _well-known_ Gitea and Gogs instances

The first attempt to build and pull a formula (hello) for linux in homebrew-core
resulted in a wrong cellar line being added to the formula's bottle block.

How to test/debug this, using the 4 bottles that where built for hello:
brew bottle --merge --debug hello--2.10_1.mojave.bottle.json hello--2.10_1.x86_64_linux.bottle.json hello--2.10_1.big_sur.bottle.json hello--2.10_1.catalina.bottle.json

This command would add create the following bottle block:

  bottle do
    cellar "/home/linuxbrew/.linuxbrew/Cellar"
    sha256 "a0af7dcbb5c83f6f3f7ecd507c2d352c1a018f894d51ad241ce8492fa598010f" => :big_sur
    sha256 "5334dd344986e46b2aa4f0471cac7b0914bd7de7cb890a34415771788d03f2ac" => :catalina
    sha256 "22948764d8f8d7be4870ff92dae64d986eb63a9150b219c20fff87d1a6aa93d6" => :mojave
    sha256 "702dc7f78444d2f4f1c19324be654bcbb8b99dd0e9ce26c3e2fbc3b6464a189f" => :x86_64_linux
  end

After the change in this PR, the result is the following:

  bottle do
    sha256 "a0af7dcbb5c83f6f3f7ecd507c2d352c1a018f894d51ad241ce8492fa598010f" => :big_sur
    sha256 "5334dd344986e46b2aa4f0471cac7b0914bd7de7cb890a34415771788d03f2ac" => :catalina
    sha256 "22948764d8f8d7be4870ff92dae64d986eb63a9150b219c20fff87d1a6aa93d6" => :mojave
    sha256 "702dc7f78444d2f4f1c19324be654bcbb8b99dd0e9ce26c3e2fbc3b6464a189f" => :x86_64_linux
  end

The brew bottle --merge code will pick the most common cellar line between the 4 bottles, by order of priority:
- non-relocatable (fixed cellar path)
- cellar :any
- cellar :any_skip_relocation

In the case of the hello bottle, the 3 mac bottles are "cellar :any_skip_relocation", and the linux bottle
is non-relocatable. So the linux bottle wins and the code correctly determines that the 4 bottles should
be non-relocatable.

In that case, the /home/linuxbrew/.linuxbrew/Cellar path is defined as cellar, and by convention
we do not write that out to the formula file, hence the cellar path check that needs to be modified
in this PR.

This PR also fixes the same situation for mac ARM cellar paths
