bump kube to 0.87.1 and k8s-openapi to 0.20.0

[alex-hunt-materialize]

Bumps kube to 0.87.1 and k8s-openapi to 0.20.0.
To avoid duplicate dependencies, it also bumps serde_with and serde_with_macros to 2.3.3, and mysql_async to 0.33.0.
Also bumps our k8s-openapi feature to v1_26, since we recently upgraded our kubernetes clusters to 1.26.

Motivation

• This PR fixes a previously unreported bug.
  We hit a hang in one of our controllers a couple weeks ago, and it looks like that might have been fixed in kube 0.87.1.
  Also, it's generally good to keep deps updated.

Tips for reviewer

There is a new optional field in the ResourceRequirements struct in Kubernetes 1.26, which we aren't using. That is the only non-Cargo change in this PR.

I'm hitting duplicate dependency issues, which I think I have mostly figured out. We have only one more dupe, which is fixed on my fork, but needs MaterializeInc/rust-server-sdk#5 merged before I can point at the materialize fork for this PR.
