clean up for apisix-ingress-controller since its no longer maintained.

[tao12345666333]

Due to the application no longer being actively maintained and an available version not being deployable through the marketplace, I will remove it from here to avoid causing confusion for users.

Thank you for wanting to submit a Pull Request to the Civo Kubernetes Marketplace repository!

If your pull request concerns an existing Marketplace application, please make sure you have:

• Notified the Maintainer of the application in this pull request so that they are aware of your proposal.
• Outlined the changes you are proposing, and the reasons these are required (e.g. stability, compatibility with new versions of Kubernetes implementations, etc).
• Tested that the application works with the proposed updates applied (including a screenshot).
• Updated the version number of the app if that has changed.
