Add PHP 8.5 support in configuration files

[Spomky]

This PR adds PHP8.5 support, updates some dev dependencies and the README file.

[jakzal]

bin/devkit.php needs to be updated (see #507).

[jakzal]

Sorry, you'll get a conflict for roave-backward-compatibility-check since I merged #546

[jakzal]

@Spomky thank you for working on this!

I resolved some conflicts. I think you'll also need to revert the scurtinizer change.

Please update bin/devkit.php to include PHP 8.5 (see how it was done before). Next, run the following command to update the readme file:

bin/devkit.php update:readme

[Spomky]

Many thanks.
The PR is rebased on master. I reverted the scrutinizer changes and updated bin/devkit.php as aksed.
Let me know if something is missing.

[jakzal]

Thanks, now it's the case of waiting for the build and possibly excluding more tools from running with PHP 8.5 if the build fails.

[Spomky]

Indeed it looks like Roave/BackwardCompatibilityCheck#940 is need first (and this dependency also needs another one).

[jakzal]

@Spomky the exclude tag seems to have got lost somewhere in the merge/rebase.

[Spomky]

OK changed. Let's see what happen

[jakzal]

twigcs doesn't work on PHP 8.5 and needs to be excluded. Once done, something else might come up. You'll see the failing check at the bottom of the build, like here: https://github.com/jakzal/toolbox/actions/runs/19703339364/job/56448635521?pr=543#step:5:2038

[jakzal]

@Spomky do you have time to finish this?

[Spomky]

@jakzal the PR is rebased, no conflicts and twigcs is now excluded as well.

[jakzal]

codeception now :D

[Spomky]

Hi,

PR rebased and tools excluded.
I am facing rate limits. I gues we should wait a moment before running the tests again.

Thank you @Spomky 🍺
