'next steps' should omit git init if we are already in a git repo

[Rich-Harris]

If you're creating a new app inside a git repo, 'next steps' includes this...

git init && git add -A && git commit -m "Initial commit" (optional)

...and it should probably just say nothing

i'd be in favor of turning the option around entirely
automatically call git init unless --no-git-init was passed or we are in a git project already.
if one was initialized, add "we initialized git for you, if you don't need that, run `rm -rf .git" to next steps

(edit: only if git is installed, we are in a tty and CI is false)

I think we should just get rid of it. It's unnecessary clutter for people that already know git, and it's a line full of funny words and symbols for those that don't. It's not very helpful in either case

[BlankParticle]

I think best option would be to ask to initialise a git repo if git is installed and the directory is already not a git repo.
