GH Actions: update for the release of PHP 8.4

... which is expected later this month.

* Builds against PHP 8.4 are no longer allowed to fail.
* Update PHP version on which code coverage is run (high should now be 8.4).
* Add _allowed to fail_ build against PHP 8.5.

Note: the "tested against" badge in the README was already updated previously in PR 621.
