Session 1.1 - Build a VCS client

Build an abstraction package that clones a VCS repo and provides access to the cloned files via fs.FS. The abstraction should basically be a function with a signature like

func GitClone (ctx context.Context, url, branch string) (fs.FS, error)

• github.com/go-git/go-git will be very helpful to implement the operation
• go-git uses a billy.Filesystem which does not diretly matches fs.FS. You need to work a way around.
• You can do the clone "in-memory" or into a temporary directory. What is the performance difference?
• Write a unit test. You can use https://github.com/halimath/mini-httpd.git (which is very small and fast to clone) and assert that the file LICENSE has a first line with trimmed text equal to "Apache License".
