   * Assert that `composer.lock` remains as expected.
   *
   * Intentions:
   *  - In `civicrm-core`, the `composer.json` is permissive. It can be updated
   *    to support different versions of Symfony.
   *  - In `civicrm-core`, the `composer.lock` is less permissive, driven by
   *   the interests of existing D7/WP/J sites.
   *
   * Without this check, a well-meaning developer may upgrade the
   * `composer.lock`, and no one would notice the change in policy
   * because reviewers' eyes tend to gloss over `composer.lock`.
