[bug#47968] [PATCH] gnu: Add git-filter-repo

["François J" <francois-oss@avalenn.eu>]

I use release tarball (instead of git as I would have liked) because it
contains pre-compiled man-pages which are too hard to build in this
context as it uses git Makefile to do it.

* gnu/packages/version-control.scm (git-filter-repo): New variable.

I changed the description by taking a more complete one from upstream. I
have chosen to not capitalize the "git" in "git filter-repo" to respect
upstream capitalization but have no opinion on the matter.
