Replaces #37416.

This PR unblocks the installation of `doctrine/persistence` version 2.

Notes:
* I had to bump `doctrine/data-fixtures` because composer would otherwise downgrade to an ancient alpha release with incomplete version constraints. This package is a dev dependency for our tests, so I think we're good here.
  **edit**: Moved to #37640.
* Until doctrine/data-fixtures#349 has been resolved, Doctrine/Bridge cannot be tested with version 2 of `doctrine/persistence`.
