Emit type definitions with cjs format

- Currently there is no difference between emitting type definitions with `cjs` or `esm` format, the only difference is the file extension. So we emit the type definitions with a `cjs` format to preserve the previous `.d.ts` extension as opposed to the new `.d.mts` extension.
