Add initial /v3/info endpoint

Is there a related GitHub Issue?

#2914

What is this change about?

Add initial v3/info endpoint that presents the fields as implmented in
https://github.com/cloudfoundry/cloud_controller_ng/blob/main/app/controllers/v3/info_controller.rb
and
https://github.com/cloudfoundry/cloud_controller_ng/blob/main/app/presenters/v3/info_presenter.rb
with some static default values for the time being.

This change is the first step in getting a working v3/info endpoint implementation.
The next step would be to extend Korifi via configuration to provide some dynamic content (For example the description field and others) to be returned by the endpoint v3/info.

Does this PR introduce a breaking change?

No, it adds a new endpoint not available before.

Acceptance Steps

• Switch to the Git branch.
• Setup local dev environment, ./scripts/deploy-on-kind.sh korifi
• cf api https://localhost --skip-ssl-validation
• cf login
• Run cf curl v3/info and see the following static content (except for the base url):

{"build":"","cli_version":{"minimum":"","recommended":""},"description":"","name":"","version":0,"custom":{},"links":{"self":{"href":"https://localhost/v3/info"},"support":{"href":"https://www.cloudfoundry.org/technology/korifi/"}}}
