Purpose

Fixes #2217

Changes the cosmos private endpoint from 'cosmosdb' to 'sql', which is the correct subresource based on https://learn.microsoft.com/en-us/azure/private-link/private-endpoint-dns#databases

Once again, I don't yet have a VNET test deployment in my current tenant, so I have not verified personally. This fix was recommended by the developer who filed #2217.

Does this introduce a breaking change?

When developers merge from main and run the server, azd up, or azd deploy, will this produce an error?
If you're not sure, try it out on an old environment.
