[OSSM-5306][OSSM-5307] Add building tests images workflow into pipeline

[mkralik3]

Describe the change

Adding a workflow (tests-images-creator.yml) for building and pushing integration and cypress test images (both at once or a particular one). The workflow can be run from a different workflow or manually (e.g. for manually rebuilding a particular tag).

1. The workflow is called from tests-images-update-latest.yml job, which is watching folders related to tests. If something is pushed into those folders, the job detects in which folders the changes were done and rebuilds the cypress, integration, or both test images accordingly. So the latest tag will always contain the latest changes in test suites.

2 In addition, the workflow is called whenever a new tag is created (e.g. after release) by tests-images-release.yml. In that case, the new integration and cypress test images are created in Quay under the released tag version, e.g. 1.65.12. Also, the images under the tag 1.65 are updated to point to the latest Z version (other words, the X.Y tag will contain always the latest X.Y.Z released version).

Examples

• Manual trigger
  • both: https://github.com/mkralik3/kiali/actions/runs/7183479032
  • integration tests only: https://github.com/mkralik3/kiali/actions/runs/7183520056
  • cypress tests only: https://github.com/mkralik3/kiali/actions/runs/7183525511
• Update master with update in
  • hack folder, which is related for both: https://github.com/mkralik3/kiali/actions/runs/7183511121
  • readme in integration, only int is rebuilt: https://github.com/mkralik3/kiali/actions/runs/7183607891
  • frontend/package.json, only cypress is rebuilt: https://github.com/mkralik3/kiali/actions/runs/7183629336
• After tag creation: https://github.com/mkralik3/kiali/actions/runs/7183109197
  • I have created three tags, v1.65.30, v1.65.31 and v1.65.32. So after that, the Quay repo contains v1.65.30, v1.65.31, v1.65.32 and v1.65 [same as v1.65.32] images

Additional info
I will backport this to the master and other necessary branches[which are maintained]. This needs to be backported as well (+ update cypress docker file), that is why firstly I want to add all these changes to 1.65 which is ready for it.

Ready for review. The description was updated to reflect recent changes.

@mkralik3 Good work, Everything looks fine. My only comments are just cosmetic. In English things will be a little more clear by removing some unnecessary plurals. I made a few suggestions in the comments. Also, in the file names please change "tests-" to "test-", thanks!

test-images-creator.yml
test-images-release.yml
test-images-update-latest.yml

LGTM.
I can see images in quay. Not sure how to run workflows before merge, but will try right after.

@mkralik3 please feel free to close the Jiras

nothing is missing here 👍

@ScriptingShrimp Since this is going only into v1.65, it will be running only when a new v1.65 tag is created there. To test manual workflow (see it in the actions page), you need to merge the backport into the master. Since this is done, I have set backports pull requests to master and v1.73 as ready.
