When we apply the above rules to sort this set we will end up with following ordering:

. Microsoft JDK 17.0.1
. Microsoft JDK 17.0.0
. Oracle JDK v17.0.0
. Microsoft JRE v17.0.1
. Oracle JRE v17.0.1

Gradle prefers JDKs over JREs, so the JREs come last.
Gradle prefers the Microsoft vendor over Oracle, so the Microsoft installations come first.
Gradle prefers higher version numbers, so JDK 17.0.1 comes before JDK 17.0.0.
