Looks good to me.
We can remove this unused dev dependency as mintlify is a global dependency.
But I guess there is a check added for UI Build which mandates if you are changing something (code, deps) on universal-components repo, it requires a new package update.
Please go ahead and run below steps:

1. Increment minor version in package.json of universal-components repo
2. Run pnpm run build to build the components assets which also copies it to main
3. Commit the Bundled assets created along with package.json file so the build check here pass.
