The change on aarch64 was necessary, since that is the minimum version that will run on Apple Silicon. The change on x64 was not necessary, but was done to match JDK 17. In connection with the fix for [JDK-8263169](https://bugs.openjdk.java.net/browse/JDK-8263169), this causes a crash on older macOS systems running 10.10 or 10.11. The long term solution is to detect and throw an exception at startup if the version of macOS is below the minimum, but for JavaFX 17 it was felt that restoring the minimum of macOS 10.10 for x64 platforms was safer.

I initially used the wrong bug ID, but I have now corrected it.

Since the branch also has a (different wrong) bug ID, I'm going to close this one and resubmit it.
