Php connection gets lost when idle after connect

[unglaublicherdude]

This is not complete yet. Missing is the Exceptions throw in the EventLoop while no request is running.

Ok. This is the first version, where all tests pass.

With the update to "amphp/file": "3.1.1" this can now be reviewed.

The failing run is the Delete old container images and I am not sure, why that runs anyway within this pr.

[unglaublicherdude]

Ok. I fixed the delete container images run but I am still not sure, why it runs in this PR (and other PRs aswell)

[unglaublicherdude]

I still see one major issue. Illuminate/Container does only support PHP >= 8.2. So I will have to downgrade it to a version that does still support 8.1

[unglaublicherdude]

my fault. illuminate/containers is not used and was only in my composer.lock file
