Temurin jre21 hotspot

## Temurin

The Temurinjre package uses OpenJDK_HotSpot VM from Temurin using the msi file format.

Using a msi file provides a rich source of installation options :

** The following Features must be listed after `/ADDLOCAL=` using a comma after each feature. **

** Note: FeatureOracleJavaSoft can be used to prevent Oracle Java launching from PATH when Temurin is uninstalled. Reinstall Oracle Java if you need to restore the Oracle registry keys. **
