Issue

When the fallback language field is configured but no present in the doc_fields, a warning is thrown:
Undefined array key "sm_language_with_fallback" SearchApiSolrBackend.php:2974

And an error is later produced in the array_intersect call:
[error] TypeError while trying to render item entity:node/1371:nl with view mode default for search index Default Index: array_intersect(): Argument #2 must be of type array, null given in array_intersect() (line 2975 of /public_html/web/modules/contrib/search_api_solr/src/Plugin/search_api/backend/SearchApiSolrBackend.php).

This should be checked with an isset.
if ($fallback_language_field && !empty($languages) && isset($doc_fields[$fallback_language_field])) {
