KDE's release script not functional on stable openSUSE

[Jaroslaw Staniek]

Hi Jonathan,
The releaseme tools require ruby 2.3 while openSUSE 42.3 depends on 2.1.
And it lacks multiple ruby version support (no RVM).
After forcibly switching to ruby 2.3 or 2.4 openSUSE stops being functional
because yast (core admin tool) depends on ruby 2.1.
Releaseme worked *great* but I had to roll back to 2.1, making the OS again
not capable to develop KDE software releases I work on. Advice welcome.
Maybe you know a way for isolated ruby installation or other workaround.
Maybe it would be best if such requirements were better suited for typical
capabilities.
Logs blow:
