Update README to state Control Tower is no longer being maintained

[scarytom]

Seems like this project has been abandoned. Would be helpful to state this at the top of the README.

This was literally contributed to last week Tom. Can you or someone else close this?

Well, that's a good sign, though these are the first commits since April, and there are still no recent releases, no activity on the Slack workspace, and everything running on end-of-life Ubuntu Bionic, I'm still not convinced. I'd welcome a statement from Engineer Better on this really.

Furthermore, we used to get regular releases with updates to Concourse. There hasn't been a new release for since March 2023 and the current Concourse shipped version of 7.8.3 lags the latest Concourse version (v7.11.0 at time of writing) by some distance.

Unfortunately, the project has no active development resources committed to it at this stage, and there are no plans to do this in the future.

Thanks for letting us know, and thanks for updating the README

After EngineerBetter was acquired by Container Solutions, the company's focus shifted away from the VMware stack, and over time all of the staff with significant context left the company.
