Devcontainer started failing upon codespaces creation

Sync my local copy with `main`. When I open a codespace using the `konductor` devcontainer, I get booted into a recovery container due to a failed devcontainer build.

```

The full log's here: https://gist.github.com/sourishkrout/595ee0cf08ea49459c0084bf4cfdf88e

Start with the linked full log and the konductor devcontainer used during Codespaces creation, then inspect the configuration responsible for the failed build. Reproduce the failure and verify that the devcontainer builds successfully and opens a Codespace without falling back to recovery.
