[jfx24] RFR: 8350136: Create release notes for JavaFX 24

[Kevin Rushforth]

Clean backport of the JavaFX 24 release notes to the `jfx24` stabilization branch, so they will be available in that branch when JavaFX 24 is published (and from there also synced into the jfx24u repo).

NOTE: The release notes are not part of the build, so this backport to jfx24 will not cause a respin of JavaFX 24.
