Plugin comes as a string instead of GeocoderProviderInterface

Problem/Motivation

On Drupal 9.1.5
In Geocoder.php public function geocode receives an array of strings instead of an array of GeocoderProviderInterface

Steps to reproduce

1. Install geocoder-php/google-maps-provider
2. Configure GeoCoder with this manual https://www.drupal.org/node/2073709
3. Search.

As a result
The website encountered an unexpected error. Please try again later.
