Drop/php7.4

To avoid unnecessary discussions, I still suggest to keep it for now (at least until the release of Debian 12): #2008 (comment)

If it should be dropped anyway, the upgrade to feed-io v5 could also happen in the version.

Yea I mainly started it because I thought that such a change and of course updating all libs especially feed-io might take quite a bit time.

And as expected there are some conflicts. The one the test complains about, I wasn't sure what to do, help welcome.

I plan to continue this soon.

1. Publish version that supports NC27 create a new branch stableXX
2. On master remove php 7.4 and move to php 8 and feed-io 5, update other packes
3. release beta of new version, by that time debian 12 is probably out already
4. new release, by that time debian 12 is very likely out already

And everybody else can stay on the old version, force enable news if needed.

This will also have the benefit that it removes feed-io filter stuff and that should in return fix #2236
I don't think that removal should be backported to feed-io 4, some people might actually like that... :)

I re-created this split into two PRs #2238 #2237
