gh-actions: Remove Ubuntu 22.04 crun workaround

[mxmxchere]

• Starting with the GitHub image runner version 20240225.1.0 podman/crun stopped working correctly. Rough summary is that the used kernel and crun 0.17 did not play well together.
• @fwilhe introduced a workaround by using the binary release of crun 1.14.3
• The bug was fixed in ubuntu package 0.17+dfsg-1.1ubuntu0.1
• The workaround is most likely no longer needed. @fwilhe and I tested successfully with the current runner version (20240721.1.0, ubuntu-latest) and without the workaround
• I also checked that the current runner has crun 0.17+dfsg-1.1ubuntu0.1
• This PR reverts the workaround so that the crun version that comes with the runner image is used.
