ORC-1520: Removed JDK 8 settings from pom

### What changes were proposed in this pull request?
The PR proposes to remove jdk8 related parameters from pom, since we moved to JDK 17 as part of #1627

### Why are the changes needed?
Since we moved to JDK 17, JDK 8 parameters are not relevant any more.
This shall keep files up to date with changes

### How was this patch tested?
Build runs successfully with the changes.

Closes #1639 from mystic-lama/ORC-1520_remove_jdk8_settings.
