### What changes were proposed in this pull request? This PR aims to drop Java 17 support in Apache Spark 5.0.0 by making Java 21 the minimum Java version. - `pom.xml`: Change `java.version`, `java.minimum.version`, and the `-release` option of `scala-maven-plugin` to 21. - GitHub Actions: Use Java 21 instead of Java 17 for `master`. `publish_snapshot.yml` keeps Java 17 for `branch-4.*`. - Docs: Update the Java version in `README.md`, `docs/index.md`, `docs/building-spark.md`, `docs/security.md`, and `python/docs/source/getting_started/install.rst`. ### Why are the changes needed? The minimum supported Java version for Apache Spark 5.0.0 is Java 21. ### Does this PR introduce _any_ user-facing change? Yes, Java 17 is no longer supported. ### How was this patch tested? Pass the CIs. In addition, I manually verified that Maven and SBT reject Java 17, and that `Test/compile`, `unidoc`, and MiMa pass with Java 21. ### Was this patch authored or co-authored using generative AI tooling?
