As part of determining whether to perform automatic updates, WordPress checks if it is running within a version-controlled environment, recursively looking up the filesystem to the top of the drive, looking for a Subversion, Git, Mercurial, or Bazaar directory, erring on the side of detecting a VCS checkout somewhere.
This commit reuses `WP_Automatic_Updater::is_allowed_dir()` in the Site Health test to avoid a PHP warning if the `open_basedir` directive is in use and any of the directories checked in the process are not allowed:
{{{
is_dir(): open_basedir restriction in effect. File(/.git) is not within the allowed path(s)
}}}
Follow-up to [44986], [55425].
Props Keffr3n, narenin.
