Switched to Run Checks for Building Images. (apache#11276)

Replaces the annoying comments with "workflow_run" links
with Run Checks. Now we will be able to see the "Build Image"
checks in the "Checks" section including their status and direct
link to the steps running the image builds as "Details" link.

Unfortunately Github Actions do not handle well the links to
details - even if you provide details_url to link to the other
run, the "Build Image" checks appear in the original workflow,
that's why we had to introduce another link in the summary of
the Build Image check that links to the actual workflow.
