[JDK-8342984](https://bugs.openjdk.org/browse/JDK-8342984) bumped the minimum boot jdk to JDK 24, and update the boot JDKs used in GHA in the process. Unfortunately the boot jdk for alpine-linux-x64 was incorrectly changed to use the linux-*aarch64* version.
Testing: GHA, incl. explicitly triggering/building of alpine-linux-x64 ------------- Commit messages: - 8354230: Wrong boot jdk for alpine-linux-x64 in GHA Changes: https://git.openjdk.org/jdk/pull/24557/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=24557&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8354230 Stats: 2 lines in 1 file changed: 0 ins; 0 del; 2 mod Patch: https://git.openjdk.org/jdk/pull/24557.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/24557/head:pull/24557 PR: https://git.openjdk.org/jdk/pull/24557
