Use git clean to remove untracked files; shallow clone for faster clones (#91)

* Use git clean to remove untracked files; shallow clone for faster clones
- When the registration server crashes abruptly it can sometimes leave behind untracked files from a previous registration. This can cause issues like JuliaRegistries/General#81954. Here I added a `git clean -fd` before checkout so that untracked files will be cleaned.
- Added `-q --depth=1` to `git clone`s so that cloning will be faster and quieter in the logs.

* Update Project.toml
