When viewing Site Health for a multisite install, there are a few recommendations that are not appropriate and could have negative implications for other sites on the install if the administrator follows the advice provided.
For example, Site Health recommends that inactive plugins and themes for a site should be removed. On a single site install, this is a great recommendation. However, on a multisite install, inactive plugins and themes for one site should not be removed because they could be active for other sites on the network.
This change also disables the `test_wp_version_check_attached()` test for multisite. This test checks for the presence of the `wp_version_check()` function on the `wp_version_check` hook, which is not present for every site on multisite.
