Move repository.url fix to a different place

[1egoman]

I merged a pull request to make a new @livekit/protocol package release here: #1336

However, that release failed due to this reason:

error an error occurred while publishing @livekit/protocol: E422 422 Unprocessable Entity - PUT https://registry.npmjs.org/@livekit%2fprotocol - Error verifying sigstore provenance bundle: Failed to validate repository information: package.json: "repository.url" is "", expected to match "https://github.com/livekit/protocol" from provenance

So I tried to fix it here: #1369

But after merging that, the build still failed... (not really a good way to test trusted publishing locally, so unfortunately it's got to be sort of just guessing and checking here). Digging into this repo's structure a bit more, I think I added that snippet to the wrong package.json 🤦 . So, this pull request puts this fix in the right place.
