Only offers a solr-7.7.0 solrconfig.xml, does it apply to solr-8.0.0?

Hello, it seems an  mismatch of schema file provided by dovecot-2.3.5.2

       field types. Text content will be indexed as "text_general" as
      <str name="fieldType">text_general</str>

# schema is from /usr/share/doc/dovecot/solr-schema.xml

dovecot-2.3.5.2 and the latest solr-8.0.0.

It seems XMLs do not match each other. How can I fix this problem?

Thanks.
