SWPROT-8953: docs: Use git describe --tag for generating zpc docs

For some reasons it was using an older annotated tag (RC0)
I didnt investigate much, but I believe it prefer tags in branches (main)
which is a good practice,
If confirmed we can switch back to the default describe
and enforce tags in branches.
