fix(index.js): pass project root options to git fn

[johnleider]

Initial check wasn't using provided options for
project root causing the plugin to crash

[johnleider]

This fix seems to only work locally. still failing on vercel.

@johnleider Thanks for catching this and opening the PR!

I'm merging this and will push a release (will be v3.1.0), and then separately look into the Vercel issue (I've opened up #7 to track). It might take me a little time to track down, since a quick Google search for documentation on how Vercel exposes git is not turning up much. I'll probably create an account of my own to play around with (I've been meaning to do that anyways).

For verification, is docs-next the repo you are trying to get this working with on Vercel?

[johnleider]

Yes that’s the repo for now. I managed to get it to work on vercel with my fork but the created and updated times are all the same. I’ve resorted to manually generating it for now. Ty for your help.
