Is your feature request related to a problem? Please describe.
The problem and question is clear described here. #1802
If the artifact uploaded has a -SNAPSHOT-prefix, Maven Central will take care of handling it as such, but jreleaser is not clear about this working
See the link. . #1802

Describe the solution you'd like
That Maven Central Portal component just allows uploads of -SNAPSHOT prefix, it is allowed in the new Maven Central Portal Publishing Style.

Describe alternatives you've considered
None.

Additional context
I guess this fix would be quite trivial, as the new Maven Central Portal has the same mechanism for publishing as a regular artificact upload, and it s a matter of verifying that jreleaser allows this for this case, and updating the docs.
