Getting Started docs say that standalone image contains Ratel, but it doesn't

To quote :

The easiest way to get Dgraph up and running is using the dgraph/standalone docker image. Follow the instructions here to install Docker if you don’t have it already.

docker run --rm -it -p "8080:8080" -p "9080:9080" -p "8000:8000" -v ~/dgraph:/dgraph "dgraph/standalone:v21.12.0"

This would start a single container with Dgraph Alpha , Dgraph Zero and Ratel running in it. You would find the Dgraph data stored in a folder named dgraph of your home directory .

Note how this has -p "8000:8000" in the command line and says “This would start a single container with […] Ratel”. However, I’m getting ERR_EMPTY_RESPONSE when browsing to http://localhost:8000.

Further research revealed that Ratel is no longer part of this image. The information in “getting started” is therefore wrong and should be updated.

For v21.12.0 I use the ratel image dgraph/ratel:v21.12.0 with cmd dgraph-ratel
Maybe the docs are not up to date.
