[6.2] Fixes code style issues in Github Workflow

[laoneo]

• I read the Generative AI policy and my contribution is either not created with the help of AI or is compatible with the policy and GNU/GPL 2 or later.

Summary of Changes

Fixes code style issues during the Github workflow. Only issue is that no new workflow is started and the test results do not appear here. this comes from a security issue where github doesn't trigger new workflows when the bot changes something in the code base (according to Claude).

Additionally it updates all images to PHP 8.5.

Remark

In Joomla 7.0 we have to remove the phpcs dependency and code style xml file.

Testing Instructions

Check if my extra code style error is fixed in this pr and a new commit is done by the bot.

Actual result BEFORE applying this Pull Request

No code style fix and a failed workflow.

Expected result AFTER applying this Pull Request

Fix is commited to the pr and the other checks are running through.

There is another PR for the same purpose for the 5.4-dev branch: #46874

I saw that and was a bit hesitant to add an action for this which I never used before.

Does it also fix the files with the --diff argument?

@laoneo Other question is why is this PR made for the 6.2-dev branch? Any new feature policy does not apply to our CI checks / GitHub actions, and to me it makes no sense to have it different in 5.4-dev/6.1-dev and 6.2-dev/7.0-dev.

Closing as we di it on 5.4 in #47936.
