chore: Support APPSMITH_DB_URL in Helm chart (#33656)

If the `APPSMITH_MONGODB_URI` is not set, we set it to a constructed
service URL value. This PR adds the same feature to new
`APPSMITH_DB_URL` env variable as well.

⚠️ This will cause conflicts on sync. DO NOT MERGE unless the author is
available.
