Updating generated licenses

[lee-rvt]

Fixes #XXXX.

Description

This updates generated files that have cosmetic changes due to previous license update.

This PR has:

• been tested on a real K8S cluster to ensure creation of a brand new Druid cluster works.
• been tested for backward compatibility on a real K*S cluster by applying the changes introduced here on an existing Druid cluster. If there are any backward incompatible changes then they have been noted in the PR description.
• added comments explaining the "why" and the intent of the code wherever would not be obvious for an unfamiliar reader.
• added documentation for new or modified features or behaviors.

thank you @lee-rvt. this lgtm just a couple of observations:

1. Verified that zz_generated.deepcopy.go is already excluded from rat runs.
2. Should apis/druid/v1alpha1/groupversion_info.go, apis/druid/v1alpha1/doc.go, and controllers/druid/suite_test.go also be updated?

[lee-rvt]

1. ✅
2. That's a good question. This is just the diffs I found after taking a clean tree and running make once. I also ran make test but that didn't change the diff. if those files aren't being generated/modified by make, I'm not sure why they need to be updated?

2. Just a nit for consistency and not needed!

@abhishekrb19 / @AdheipSingh can either of you trigger a workflow run for this and review?
