Ensure che-operator files contains correct license header after migrate to operator sdk 1.X

[flacatus]

Is your task related to a problem? Please describe.

Actually che-operator contains some gaps in license headers like:

• Incorrect year
• Different license. Examples:
  * https://github.com/eclipse-che/che-operator/blob/main/.github/workflows/nightly-image-build.yaml
  * https://github.com/eclipse-che/che-operator/blob/main/pkg/deploy/clusterrole.go

Describe the solution you'd like

Create a tool to update header licenses in che-operator,che-machine-exec,chectl and also add a PR validation to warning contribuitor in case of invalid header.
