Default to running as a Local Extension

With the new features included with the Remote Development extension for VSCode, we can now develop from inside a docker container, but this causes the Docker Explorer extension to attempt to execute all it's functionality inside the container.

Please investigate whether it is possible to continue to run this extension outside the container (I think it's termed a 'local extension'? i.e. executing commands on the host?) while Remote Development is connected and running inside the container.

Start by checking VS Code's Remote Development documentation for local-extension behavior, then inspect how Docker Explorer is activated and where it executes commands. Done means establishing whether host-side execution is supported while connected to a container and recording the resulting behavior or limitation.
