Subject: [PATCH] Plugins: Block plugin updates on the update screen if
 required PHP version is not supported.

This brings the changes in [44937] to the WordPress Updates page in the admin. Now, when a site does not meet the minimum PHP version requirements for a plugin update, the user will not be able to update. Instead, they will be presented with educational information to guide them through the process of updating PHP.

Props afragen, miyauchi, TimothyBlynJacobs, desrosj.
Fixes #44350.
