[SPARK-57966][YARN][DOC] Update Java 17 support description in
`running-on-yarn.md` for Hadoop 3.5.0
### What changes were proposed in this pull request?
This PR updates `docs/running-on-yarn.md` to reflect Apache Hadoop 3.5.0
(SPARK-55657).

After:
> Apache Hadoop supports Java 17 since 3.5.0, ...
### Why are the changes needed?
Apache Hadoop 3.5.0 supports Java 17, so the existing statement is outdated.
### Does this PR introduce _any_ user-facing change?
No. This is a documentation-only change.

# Launching Spark on YARN
-Apache Hadoop does not support Java 17 as of 3.4.1, while Apache Spark
requires at least Java 17 since 4.0.0, so a different JDK should be configured
for Spark applications.
+Apache Hadoop supports Java 17 since 3.5.0, while Apache Spark requires at
least Java 17 since 4.0.0. When running on a YARN cluster whose Hadoop version
is older than 3.5.0, a different JDK should be configured for Spark
applications.
Please refer to [Configuring different JDKs for Spark
Applications](#configuring-different-jdks-for-spark-applications) for details.
Ensure that `HADOOP_CONF_DIR` or `YARN_CONF_DIR` points to the directory which
contains the (client side) configuration files for the Hadoop cluster.
