Thanks for this PR @jamesmontemagno !

This was probably caused by devcontainers/features#1442

[chriswblake]

I'm actually not sure we need docker-in-docker on this exercise anymore. With the switch to using the GitHub-hosted version of the MCP server in #56, I don't think there is a need to run docker containers.

@FidelusAleksander, we might consider just removing this in a future PR.
