Deprecation warning while using the geocoding endpoint

Problem/Motivation

After using the geocoding endpoint in a Drupal 10.2.5 I get the following deprecation notice:

DEPRECATED FUNCTION: CREATION OF DYNAMIC PROPERTY DRUPAL\GOOGLE_MAPS_SERVICES\API\HTTPCLIENT::$CONFIG IS DEPRECATED IN DRUPAL\GOOGLE_MAPS_SERVICES\API\HTTPCLIENT->__CONSTRUCT() (LINE 87 OF MODULES/CONTRIB/GOOGLE_MAPS_SERVICES/SRC/API/HTTPCLIENT.PHP).

Proposed resolution

The issue is caused by a missing explicitly defined property $config which is used in __construct(). After defining the property explicitly, the deprecation is gone.

I provide a patch for that.
