[PR #11849/74c096b0 backport][stable-12] homebrew_cask: handle placeholder version from brew --version (#11855)

homebrew_cask: handle placeholder version from brew --version (#11849)

* homebrew_cask: handle placeholder version from brew --version

When brew is run as the wrong user, git repositories may be owned by
a different user, causing brew --version to output a placeholder like
"Homebrew >= 4.3.0 (shallow or no git repository)" instead of the real
version. The parsed version would then be lower than the 2.6.0 threshold,
causing _brew_cask_command_is_deprecated() to return False and the module
to use the disabled "brew cask" command syntax.

Detect the ">=" prefix in the parsed version and treat it as a modern
installation.

Fixes #4708



* homebrew_cask: add changelog fragment for #11849
