Fix import twenty-shared (#9754)

In this PR:
- removing rootDir / baseUrl from any tsconfig.json
- we need to keep it in tsconfig.spec.json and also specify rootDir in
jest.config.ts moduleMapper because of the way nx jest executor works
(automatically moving back to root)
- we need to explictly specify the depencies to twenty-shared /
twenty-emails (built packages) in packages package.json to help nx
understand dependencies

packages/twenty-ui/tsconfig.spec.json
