fix(ci): run at least compilation and unit tests on few fixed jug_xl

[wdconinc]

Briefly, what does this PR introduce?

This changes the CI philosophy to run the compilation and unit testing on an expanded set of platform versions. It does this for the clang release versions, since fastest. It separates the default CI platform (set as input on workflow_dispatch) from the explicit platform versions sets in the build job matrix (there may be overlap, even by default).

What kind of change does this PR introduce?

• Bug fix (issue: need to test on more versions/platforms; have tests on stable platform by default)
• New feature (issue #__)
• Documentation update
• Other: __

Please check if this PR fulfills the following:

• Tests for the changes have been added
• Documentation has been added / updated
• Changes have been communicated to collaborators

Does this PR introduce breaking changes? What changes might users need to make to their code?

No.

Does this PR change default behavior?

No.

[wdconinc]

The idea here would be for the default platform in the workflow_dispatch to point to the oldest tested environment (e.g. right now jug_xl:23.12-alpha) with at least the liatest tested environment (jug_xl:nightly) included in the build job matrix.

@veprbl This now runs at least compilation and unit tests on jug_xl:23.12-alpha in addition to the usual nightly. It's not quite a full systems test, but I think most regressions would be of the kind that lead to failed compilation, not regressions that still compile fine and pass unit tests but somehow don't run beyond that.

[wdconinc]

"API rate limit exceeded" and it is not recognizing the renamed jobs of course. If approved, I'll go ahead and change the branch protection settings to use the new names.
