Accept period in repo path regex

[mikepurvis]

Example:

import rosdistro
import re

rosdistro.repository_specification.RepositorySpecification.VCS_REGEX = re.compile(
    r'(?:https?:\/\/|ssh:\/\/|git:\/\/|git@)((?:[a-fA-F0-9]{40}@)?[\w.-]+)[:/]([\w./-]*)(?:\.git)?$')

index = rosdistro.get_index(rosdistro.get_index_url())
dist = rosdistro.get_distribution(index, "rolling")
for repo_name, repo_data in dist.repositories.items():
    if source := repo_data.source_repository:
        print(source.get_url_parts())

Without the monkey patch to the proposed regex, this fails on the current rolling:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/mikepurvis/rosdistro2nix/rosdistro2nix/cli.py", line 36, in main

          ^^^^^^^^^^^^^^^^^^^^^^
