fix: use JSON kind for devcontainer updatecli targets

Switch from file kind with regex patterns to json kind with JSONPath
queries for updating Docker and GitHub CLI versions in devcontainer.json.

The previous file-based approach failed because the search pattern matched
the feature name line, but the version field is on the next line. Using
json kind with JSONPath directly targets the correct fields.
