Fix purl namespace corruption when path contains ".git" mid-path

The generic VCS branch in _vcs_namespace_and_name used str.replace to
strip a ".git" suffix from the path, which silently removed every
occurrence anywhere in the path. A URL like
https://gitlab.com/group/foo.github/project.git produced the namespace
"group/foohub" instead of "group/foo.github". Use removesuffix so only
the trailing .git is stripped.
