     * Parses Drupal module, theme and profile .info.yml files.
     *
     * Info files are NOT for placing arbitrary theme and module-specific
     * settings. Use Config::get() and Config::set()->save() for that. Info files
     * are formatted as YAML. If the 'version' key is set to 'VERSION' in any info
     * file, then the value will be substituted with the current version of Drupal
     * core.
     *
     * Information stored in all .info.yml files:
     * - name: The real name of the module for display purposes. (Required)
     * - description: A brief description of the module.
     * - type: whether it is for a module or theme. (Required)
     *
     * Information stored in a module .info.yml file:
     * - dependencies: An array of dependency strings. Each is in the form
     *   'project:module (versions)'; with the following meanings:
     *   - project: (optional) Project shortname, recommended to ensure
     *     uniqueness, if the module is part of a project hosted on drupal.org.
     *     If omitted, also omit the : that follows. The project name is currently
     *     ignored by Drupal core but is used for automated testing.
     *   - module: (required) Module shortname within the project.
     *   - (versions): Version information, consisting of one or more
     *     comma-separated operator/value pairs or simply version numbers, which
     *     can contain "x" as a wildcard. Examples: (>=8.22, <8.28), (8.x-3.x).
     * - package: The name of the package of modules this module belongs to.
     *
     * See forum.info.yml for an example of a module .info.yml file.
     *
     * Information stored in a theme .info.yml file:
     * - screenshot: Path to screenshot relative to the theme's .info.yml file.
     * - engine: Theme engine; typically twig.
     * - base theme: Name of a base theme, if applicable.
     * - regions: Listed regions.
     * - features: Features available.
     * - stylesheets: Theme stylesheets.
     * - scripts: Theme scripts.
     *
     * See bartik.info.yml for an example of a theme .info.yml file.
     *
     * For information stored in a profile .info.yml file see
     * install_profile_info().
     *
     * @param string $filename
     *   The file we are parsing. Accepts file with relative or absolute path.
     *
     * @return array
     *   The info array.
     *
     * @throws \Drupal\Core\Extension\InfoParserException
     *   Exception thrown if there is a parsing error or the .info.yml file does
     *   not contain a required key.
     *
     * @see install_profile_info()
     */
