Also support Java 21

Test plan

• run sbt docker and ensure image builds
• inspect image to ensure it contains jdk 21

Errors

Unfortunately i couldn't get this to work, due to what i assume is a local configuration problem. That said, i believe this change should be safe as i exactly copied previous patterns.

When running ./sbt then docker i received the following
