fix(build): duplicate version string "v0.8.0-v0.8.0" #20578
- Prevent duplicate version strings such as v0.8.0-v0.8.0.
- Change the format for git releases from v0.9.0-dev-67-g625ba79be to
  v0.9.0-dev-67+g625ba79be.

Nvim versions are now:
release                    : v0.9.0
prerelease without git info: v0.9.0-dev
prerelease with git info   : v0.9.0-dev-67+g625ba79be
