Make it easier to find locations where ACA is available

az provider show locations

Is your feature request related to a problem? Please describe.
ACA is not available in all locations, and it saves a lot of time if a user can see where it is available before attempting a deployment.
The current command is pretty unintuitive and hard to remember:
az provider show -n Microsoft.App --query "resourceTypes[?resourceType=='managedEnvironments'].locations"

Describe the solution you'd like
We should have something that is simple and easy to remember like this:
az provider show locations -n ContainerApps

There should also be a command/param to filter to regions that not only have ACA deployed, but also have available capacity:
az provider show locations available -n ContainerApps
or
az provider show locations -n ContainerApps -onlyAvailable
(There is probably already a pattern for this, just providing a couple of examples.)

Describe alternatives you've considered
I've asked around and the ugly command above is the best anyone could think of.

Thank you for your feedback. This has been routed to the support team for assistance.
