PHP 8.4 Issue

Problem/Motivation

Depreciated function warning

Deprecated function: Drupal\views_xml_backend\Plugin\views\query\Xml::ensureTable(): Implicitly marking parameter $join as nullable is deprecated, the explicit nullable type must be used instead in include() (line 576 of drupal11/vendor/composer/ClassLoader.php)

Steps to reproduce

Use PHP8.4 and use module in a view
Clear cache

Proposed resolution

In views_xml_backend/src/Plugin/views/query/Xml.php look for

public function ensureTable(..., JoinPluginBase $join = NULL)

and change it to:

public function ensureTable(..., ?JoinPluginBase $join = NULL)
