Issue with the "Fly Kubernetes Quickstart" doc

[aslatter]

I found an issue with this document.

Title: Fly Kubernetes Quickstart
Location: https://fly.io/docs/kubernetes/fks-quickstart/
Source: https://github.com/superfly/docs/blob/main/kubernetes/fks-quickstart.html.markerb

Describe the issue

Under the heading "What we don't support" is an list:

On container specs, we don’t support the following fields

• readinessProbe

This "fresh produce" post makes it sound like they have been supported for a while: https://community.fly.io/t/fly-kubernetes-updates-readiness-probes-custom-hostnames-exec-support/21294

An additional limitation noted in the quickstart is that multi-pod containers aren't supported, but this community post makes it sound like they are: https://community.fly.io/t/everybody-gets-containers-sidecars-and-init-containers-in-fks/23020
