Right now, we are only running the YAML validation PR checks through Konflux.

The Konflux PR check fails whenever there is a validation issue on the YAML files.

Investigating this validation error on Konflux PR check currently means logging into Konflux, finding the correct job for the specific PR check, scroll through all the tabs and the logs and finally figure out that the Konfluc PR check is failing because of a validation issue on the YAML files.

Instead of going through this whole ordeal, we should just create a GitHub Actions PR check that validates that these YAML files are in the correct format. This will allow us to see the YAML validation errors right from GitHub.
