Move to manage the entire plugin version menu and dependencies from the
same script. This will allow the entire site to roll forward to newer
releases and bugfix the plugin versions menu as issues are found, mostly
without needing to touch any of the individual releases.
Rework the links provided and menu styling to allow for a clear menu
edge, and a slight highlighting when hovering. Ensures that clicking
anywhere in the highlighted section should bring you to the selected
version.
Always use the same version of the plugin versions menu script, loading
from the latest across all releases. This is to allow for updates to
this component to be deployed across any release at the same time to
allow for a consistent switching experience.
