Fix URL links of logs in Github Actions

[geokats7]

The Problem
In GitHub Actions the URL generated from the following log output is not parsed correctly because of the trailing period(.)
logger.info(f'Initializing environment for {repo}.') and it leads to a 404/Not Found page.

These are some examples:

[INFO] Initializing environment for https://github.com/Yelp/detect-secrets.git.
[INFO] Initializing environment for https://github.com/pre-commit/pre-commit-hooks.
[INFO] Initializing environment for https://github.com/pre-commit/mirrors-isort.
[INFO] Initializing environment for https://github.com/ambv/black.
[INFO] Initializing environment for https://github.com/PyCQA/flake8.git.

The Effect
Having a broken link in the logs output undermines the project's credibility and could frustrate users. It's unfortunate because "pre-commit" is a widely-used and highly maintained project.

The Fix
The PR just removes the trailing period from the log output.
I believe this is a useful change because it doesn't remove any information while it restores the functionality of the URL links in GitHub Actions console.

Hmm...I'm not sure why some of the tests are still failing.
@asottile Any help would be appreciated, thanks!

@asottile You're right I just saw the duplicate. However, I wonder why the change shouldn't be incorporated since the issue keeps coming up every now and then.

for the same reasons it was declined in the duplicate
