The installation guide listed the experimental Spark 4.2 support as targeting `4.2.0-preview4` and claimed no Comet tests run in CI. Both are stale: - The `spark-4.2` Maven profile targets the `4.2.0` final release. - `pr_build_linux.yml` includes a "Spark 4.2, JDK 17" job in the `linux-test` matrix, so Comet tests do run in CI. Spark SQL tests still do not run for 4.2 (no `spark_4_2` job in `ci.yml`), so that column stays "No" and the version remains experimental. Also refresh the two `4.2.0-preview4` examples in the contributor guide, which cited a version Comet no longer targets, to use a hypothetical future release instead.

branch-1.0.Rationale for this change
branch-1.0carries the same two stale Spark 4.2 claims in the installation guide asmain:4.2.0-preview4, but thespark-4.2Maven profile on this branch targets the4.2.0final release.pr_build_linux.ymlon this branch has the"Spark 4.2, JDK 17"entry in thelinux-testmatrix.Since these docs are published for the 1.0.x release line, the correction is worth carrying here rather than waiting for 1.1.0.
