Message:

Site health: Introduce view_site_health_checks capability.

Introduces the faux primitive capability view_site_health_checks available to single site admins and multisite super-admin to view the site health page within the admin.

The capability is mapped to the install_plugins capability without being dependent on the file system being writable. This fixes a bug where the feature couldn't be used by sites unable to write to the file system or managed through version control.

The capability is granted on the user_has_cap filter.

Props birgire, Clorith, palmiak, peterwilsoncc, spacedmonkey.
Fixes #46957.
