Ongoing maintenance of these helm charts

[JamesBelchamber]

I note this in the README:

NOTE: we're currently not accepting new PRs as we're evaluating our priorities concerning the ADOT Helm Charts. We plan to update this repo with a concrete timeline with the new policy by end of March 2023.

As March 2023 has now passed is there a new policy on this chart? I note the low activity and open Pull Requests, which implies this is no longer used or recommended - but it would be good for this to be made explicit.

@JamesBelchamber thanks for raising this issue and yes, that's fair. We should make it explicit.
