fix: use bracket notation for JSON path in devcontainer updates

The JSON path query for devcontainer.json was using dot notation with
quotes which failed to match keys containing special characters
(dots, slashes, colons).

Changed from:
  $.features."ghcr.io/devcontainers/features/docker-in-docker:2".version

To bracket notation:
  $.features["ghcr.io/devcontainers/features/docker-in-docker:2"].version

This fixes the updatecli workflow error:
  could not find value for query "$.features.\"ghcr.io/devcontainers/features/docker-in-docker:2\".version"
