Option to not use git-LFS when initializing a repo

Similar to this suggestion in this GitHub for Unity issue

I like everything about Git for Unity, but I hope there was an option that I can choose to not use git LFS so I don't have to manually uninstall it and migrate from it everytime I make a project.

Since I assume it's tedious to remove LFS and it's remnants in an existing repo with commits,
I think it's better to let users opt-out from it at the start.

git lfs doesn't need to be removed - it only gets used when files are marked as being tracked by lfs, in .gitattributes. I can set up an alternate initial .gitattributes file that doesn't track files in lfs, and then it won't be used.

Thanks, that'll be useful as GitHub is also very limited on how much LFS storage you're allowed on a free plan. I also use this for pushing to KeyBase repos which don't really support LFS like GitHub does so I have to disable it when I create a new project.

@yongminparks - I use this for disabling LFS on a new project:

# From the .git directory for a project
# Useful for using the GitHub for Unity Project outside of GitHub (ie: Keybase)

# Uninstall the LFS hooks from .git/hooks/
git lfs uninstall

# Disable anything that is already in LFS - pretty slow for lots of files
git lfs migrate export --everything --include .

# Disable the LFS handler in .gitattributes
sed -i '/filter=lfs/d' .gitattributes

# Verify that there are no files in LFS
git lfs ls-files

# Probably need to force-push with the mess this has made: 
git push origin main --force

# Everything in one:
# git lfs uninstall && git lfs migrate export --everything --include . && sed -i '/filter=lfs/d' .gitattributes && git lfs ls-files
# git push origin main --force
