Release 5.2.0 to flush out whats merged?

[consideRatio]

@benz0li asked in jupyterhub/zero-to-jupyterhub-k8s#3406 (comment) for a release with dark mode toggle. We currently have z2jh and tljh beta releases out - is flushing 5.2.0 (with dark mode toggle, and more?) ok to do @minrk?

and more?

• Add LD_LIBRARY_PATH to LocalProcessSpawner.env_keep, move most env_keep defaults to LocalProcessSpawner #4904

While I think it's fine to make a release with what we have, I really want to push back very hard on the amount of work we are creating for ourselves in making these distribution releases. I feel very strongly that preparing a release for a distribution should not trigger a bunch of work to release dependencies as well. Either they are ready (i.e. already released) or they are not and should wait for the next distribution release.
