In PatternFly 6, the colour of the masthead changes depending upon the mode (light vs dark). As a result, a single custom logo may not work for both cases (as is the case with the existing OKD and OpenShift logos as they assume the masthead background is always dark and include white text as a result). We need to add the ability to specify a second logo to account for this.

See https://docs.openshift.com/container-platform/4.17/web_console/customizing-the-web-console.html#adding-a-custom-logo_customizing-web-console

AC:

• Make sure console-operator will pick up the new API the path to the additional logo and pass it to the console though the console-config.yaml
• Add integration and unit tests
