Update the JDK version in Github Actions for formatting (#513)

## What changes are proposed in this pull request?

Update the JDK version in Github Actions Workflow that does formatting.
This is done because the old JDK version (JDK 8) is causing issues with
formatting options. Developers locally use JDK 11 for formatting which
caused the formatting test to fail on the PRs

## How is this tested?
