Remove suffix from repo folder

[ctriquet-cs]

When cloning a Git project .git suffix is repository URL is kept what results in the creation of a folder named repository_name.git.

That PR proposes to remove that .git suffix.

Thank you for the PR, @ctriquet-cs!

One question I have now is about backwards compatibility - what would happen in cases when the repo was previously already cloned with the .git prefix, and now that gets stripped out? That may lead to a new clone instead of just updating the currently existing clone, which may be alarming to the user if they have already done some work on the existing clone.

I think we can make this behavior backwards compatible in the following way:

1. If .git is present in the URL of the repo, but we don't have an existing clone on the filesystem, strip .git
2. If .git is present in the URL of the repo but we do have an existing clone on the filesystem including the .git suffix, let it be.

We'll probably also need a test added to catch this.

How does that sound, @ctriquet-cs?

@yuvipanda Sorry for the delay in my response. Yes, that sounds like a good idea to maintain backwards compatibility. I have made the necessary modifications and added the corresponding unit tests.
