Airflow Helm Chart: Scheduler Should Support Full Probe Configuration (livenessProbe/readinessProbe/readinessProbe)

### Official Helm Chart version 1.18.0 (latest released) ### Apache Airflow version 3.0.2 (affects any) ### Kubernetes Version 1.34 (affects any) ### Helm Chart configuration ```yaml scheduler: livenessProbe: initialDelaySeconds: 20 periodSeconds: 10 timeoutSeconds: 5 failureThreshold: 3 # Attempt to set a command, or configure as TCP/HTTP (see below attempts) # command: ["airflow", "jobs", "check", "--job-type", "SchedulerJob", "--local"] # Attempted to add: # readinessProbe: # tcpSocket: # port: 8793 ``` ### Docker Image customizations None. Using the official Apache Airflow image. ### What happened I attempted to enable and customize both liveness and readiness probes for the scheduler pod. However, the `scheduler` section of the Helm values only permits a very limited set of probe fields. The only keys allowed are the timing parameters and `command` for the liveness probe. Attempts to add typical Kubernetes probe types (like `tcpSocket`, `httpGet`, or even `readinessProbe:` at all) result in schema validation errors during `helm template` or `install`, e.g.: ``` Error: values don't meet the specifications of the schema(s) in the following chart(s): airflow: - scheduler: Additional property readinessProbe is not allowed - scheduler.livenessProbe: Additional property tcpSocket is not allowed ``` ### What you think should happen instead Both `livenessProbe` and `readinessProbe` should support the full set of [Kubernetes probe options](https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/) (such as `exec`, `tcpSocket`, `httpGet`, etc.) for the scheduler, as is already the case with other components in the chart (like workers and webserver). Ideally, there should also be a `readinessProbe` supported for `scheduler` the same way as with the other pods. ### How to reproduce 1. Try to set a readiness probe for the scheduler in `values.yaml`: ```yaml scheduler: readinessProbe…
