Docker RUN installext ms-azuretools.vscode-docker fails with 'not found'

[dougnukem]

Installing the docker (https://marketplace.visualstudio.com/items?itemName=ms-azuretools.vscode-docker) vs-code extension fails:

 RUN installext ms-azuretools.vscode-docker

Installing extensions...
Extension 'ms-azuretools.vscode-docker' not found.
Make sure you use the full extension ID, including the publisher, e.g.: ms-vscode.csharp
error vscode undefined
The command '/bin/bash -c installext 'ms-azuretools.vscode-docker'' returned a non-zero code: 1
2020-03-10 15:39:15 FATAL	failed to build image: failed to build: exit status 1

Also fails with old name

RUN installext peterjausovec.vscode-docker

It appears the docker extensions has been changed and renamed.

peterjausovec.vscode-docker -> ms-azuretools.vscode-docker

Maybe related to code-server scraping extensions from github vs using the marketplace due to Microsofts restrictions:
