I have made the decision to restore compatibility with EL 9 and pause
efforts in https://todo.sr.ht/~gotmax23/forge-srpm-macros/3 to continue
adopting new RPM 4.17+ features.
Packagers have requested the ability to use %forgeversion on EL 9, and
we need to support it for tools like Packit and Zuul CI that build SRPMs
in CentOS Stream containers to be able to adopt it.
