Update PHP provisioning versions

[adevade]

This PR updates the PHP provision script to fallback to PHP 8.4, since 8.3 does not get active support anymore.

It also updates the suggestion list to remove 8.0 and 8.1 since they're not getting security updates, and adds the latest versions 8.4 and 8.5.
