fix: use bracket notation for JSON path in devcontainer updates (#1830)

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"
