Prevent version less tags from downgrading

[cobexer]

Make sure we don't generate version less tags that used to refer to Gradle 9+ images on older branches suddenly downgrading your Gradle version

[cobexer]

The upstream diffing of the published images alerted me to this in docker-library/official-images#19972 (comment):

[keeganwitt]

Why would this be needed after the directories have been deleted in the older branches as well as master?

[cobexer]

@keeganwitt we only deleted images that were no longer there, thus

docker-gradle/.github/workflows/ci.yaml

Lines 48 to 49 in 23cd8c0

	- jdk24-corretto
	- jdk24-noble-graal

are still there until they get removed upstream.
