Update license compliance widget extension computed props

What does this MR do and why?

It aligns the frontend fields with the backend fields has_denied_licenses !90841 (merged) and approval_required !87150 (merged)

Changes

• approval_required is the key we used in frontend already so it needs no change

• denied_license was changed to has_denied_licenses. It also went from an integer to a boolean.

Describe in detail what your merge request does and why.

Screenshots or screen recordings

Denied Licenses

Denied License and approval required

Screenshot TBD. Unit tests and UI supports this state, but the endpoint is not currently returning the correct status. Assuming that it does, this MR should be fine.

These are strongly recommended to assist reviewers and reduce the time to merge your change.

How to set up and validate locally

• Reach out to me for a demo, or attempt steps below
• In a rails console enable flag Feature.enable(:refactor_license_compliance_extension)
• Clone the https://gitlab.com/gitlab-examples/security/security-reports project locally
• Manually trigger the pipeline to run for Master. This can be done by going to the CI/CD -> Pipelines tab on the left nav and then clicking the Run Pipeline button.
• Create a new MR. I suggest changing something simple like a letter or two in the README.md file. We just need a pipeline to complete and run. The sample project uses test reports to generate the data so doesn't matter what you change just need a MR.
• Set up Allowed/Denied licenses in https://<localhost>/<group>/<project>/-/licenses#policies
• Add a License-Check approval group with at least 4 required approvals
• Create a new MR
• See License compliance widget

Numbered steps to set up and validate the change are strongly suggested.
