homebrew is considered only in arm macos

[daeho-ro]

When I see the macos.py,

        is_homebrew = sys.prefix.startswith("/opt/homebrew")
        path_list = [self._append_app_name_and_version("/opt/homebrew/share")] if is_homebrew else []

it only considered the homebrew prefix for arm macos. For intel users, it should be /usr/local. Furthermore, it can be modified by user when they install the homebrew, which means it can be arbitrary.

Without prefix, there is a quite unique path element, that is /opt/python. Homebrew always install the python in the path that

$HOMEBREW_PREFIX/opt/python@$VERSION/Frameworks/Python.framework/Versions/$VERSION

so we may catch the homebrew users by checking the path contains /opt/python. Also, splitting the path by this element can give you the homebrew prefix if you do not plan to read the env HOMEBREW_PREFIX.

Here is my working PR, any feedback is welcome.
