  10   * Retrieves plugin installer pages from the WordPress.org Plugins API.
  11   *
  12   * It is possible for a plugin to override the Plugin API result with three
  13   * filters. Assume this is for plugins, which can extend on the Plugin Info to
  14   * offer more choices. This is very powerful and must be used with care when
  15   * overriding the filters.
  16   *
  17   * The first filter, {@see 'plugins_api_args'}, is for the args and gives the action
  18   * as the second parameter. The hook for {@see 'plugins_api_args'} must ensure that
  19   * an object is returned.
  20   *
  21   * The second filter, {@see 'plugins_api'}, allows a plugin to override the WordPress.org
  22   * Plugin Installation API entirely. If `$action` is 'query_plugins' or 'plugin_information',
  23   * an object MUST be passed. If `$action` is 'hot_tags' or 'hot_categories', an array MUST
  24   * be passed.
  25   *
  26   * Finally, the third filter, {@see 'plugins_api_result'}, makes it possible to filter the
  27   * response object or array, depending on the `$action` type.
  28   *
  29   * Supported arguments per action:
  30   *
  31   * | Argument Name        | query_plugins | plugin_information | hot_tags | hot_categories |
  32   * | -------------------- | :-----------: | :----------------: | :------: | :------------: |

  36   * | `$number`            | No            |  No                | Yes      | Yes            |
