Drush 12/13 compatibility

Setting the status to "Needs review" since the composer install problem raised in pipelines is already on 4.0.x

Dear reviewers,
please make sure that the commands are available on Drush 12/13 and still available on Drush 11.

Note for the maintainers: when you'll want to drop drush 11 support, you'll just need to remove the drush services declarations from search_api_solr.services.yml and modules/search_api_solr_admin/search_api_solr_admin.services.yml
You could also force a drush 12 minimum version by adding the following lines to your composer.json in order to raise a conflict alert if someone tries to use an earlier version:

"conflict": {
   "drush/drush": "<12"
}
