Describe the bug

When installing this package via foundry, it is added as a submodule. But this repo has an invalid submodule at lib/modulekit - looks like it was added in c5c8691 but for some reason it was done without editing .gitmodules. This causes the submodule init to fail:

pablo:~/repos/modulekit (main)$ git submodule update --init
fatal: No url found for submodule path 'lib/modulekit' in .gitmodules

And since repos installing this will need to run git submodule update --init --recursive to install foundry dependencies, this breaks submodule installation for any repos installing this, with the same error message.

AFAICT the submodule isn't referenced anywhere so I believe it should be safe to delete it.
