[SPARK-53983] Increase s.k.o.reconciler.foregroundRequestTimeoutSeconds to 60s

### What changes were proposed in this pull request?

This PR aims to increase `s.k.o.reconciler.foregroundRequestTimeoutSeconds` to `60s`.

### Why are the changes needed?

While testing on EKS clusters, `30s` timeout happens too frequently.

### Does this PR introduce _any_ user-facing change?

This only increases the timeout. `Spark Operator` will wait more instead of timing out.

### How was this patch tested?

Pass the CIs.

### Was this patch authored or co-authored using generative AI tooling?

No.

Closes #395 from dongjoon-hyun/SPARK-53983.
