chore: Use new Docker image for dev-time server (#25609)

We've stopped [building the slim
images](https://github.com/appsmithorg/appsmith/pull/25219) now and so
the instructions to run server locally, which rely on the slim server
image, need to be updated to use the newer `appsmith-ce` image.

This PR updates the instructions to use this.

 ## Setup with Docker
 
-* You can run the server codebase in a docker container.
+Running the Appsmith Docker image as a container will grant you a running Appsmith server, along with its dependencies, like MongoDB and Redis. This is the easiest way to get started with Appsmith server.
-
-* This method is recommended if you just want to run the backend server for testing/contributing to frontend code. If you would like to make edits to the source code of server, use [local server method](#local-setup)
