[SPARK-57771][INFRA] Use Python 3.11 in spark-rm release image

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

This PR uses `Python 3.11` instead of 3.10 in `dev/create-release/spark-rm/Dockerfile` for Apache Spark 4.3.0+.

### Why are the changes needed?

Since `Python 3.10` reaches end-of-life in October 2026 before Apache Spark 4.3.0 release, Apache Spark 3.4.0 dropped it.
- #55914

So, ideally, we need to use Python 3.11+ in the release script. However, recently, on 2026-01-23, we share `Dockerfile.base` for all maintenance releases and `ubuntu:jammy` has only `Python 3.11.0rc1`. Since `Python 3.11.0rc1` is better than the EOL `Python 3.10`, this PR upgrades it only for Spark release.
