Add daily testing with PHP 8.4

Added testing using latest Mysql 8.4 and Postgresql 17

so I changed pgsql:17 for merge request job to use PHP 8.4 to re-use in daily testing

meantime mysql 9.1 is out so tested it

So filed 📌 Upgrade Mysql 9.0 CI job to use 9.1 image Active

Re-ran all the failures and it's green.

Don't see any reason not.

Asked other committers about this one

As 10.4/10.5 are compatible the commit needs backport to 10.x

Committed 5e69f0b and pushed to 11.x. Thanks!

Added MR for 10.5.x

10.5 reroll seems fine

Committed and pushed 939d89bd9b2 to 10.5.x and c0adde8b3b1 to 10.4.x. Thanks!
