Enhancement:- Git repository should not be needed for installing `forge-std`

[hammersharkfish]

forge install foundry-rs/forge-std gives

git status exited with code 128:
fatal: not a git repository (or any of the parent directories): .git

Even after git init you need to stage and commit before you can install forge-std

Getting all the tests right is essential before you make your first commit , forge-std forces you to make a commit before you write test scripts .
