feat(git-clone): custom destination folder name

[MeguminSama]

Currently, repositories are always cloned into a folder named after the repo URL.

For example, if you clone git@github.com:coder/modules.git, it'll be cloned into a folder called modules.

This PR adds a new attribute, folder_name. When provided, this name will be used as the destination folder.

In this example, coder will be cloned into ~/projects/coder/coder-dev, where previously it would've been cloned into ~/projects/coder/coder:

module "git-clone" {
  source      = "registry.coder.com/modules/git-clone/coder"
  version     = "1.0.12"
  agent_id    = coder_agent.example.id
  url         = "https://github.com/coder/coder"
  folder_name = "coder-dev"
  base_dir    = "~/projects/coder"
}

Thank you for the Contribution. Can you also add a test for this?

[MeguminSama]

Sure thing, give me a bit :)

The PR doesn't touch much code, but please let me know if you think there are other tests I should perform (cloning over https, different provider, etc.)
