### What?
Errors were updated to MDX as part of
https://github.com/vercel/next.js/pull/52038, and as a part of this, the
`errors/manifest.json` file was removed.
This PR did not update the generators used to create new errors, causing
the error gen to...error 😄
This fixes the generator.
### What?
Use [Turborepo generators](https://turbo.build/repo/docs/core-concepts/monorepos/code-generation#custom-generators) instead of plop.
Turborepo generators are built on top of plop, but include some additional tooling to make working in monorepos easier. It also supports zero config typescript for configs.
### Why?
Same Team!
### How?
Ported the existing plopfile to a turbo generator config
