Subject: [PATCH] Bug 33353: Add compatibility with Elasticsearch 8.x

Elasticsearch 8 removed the support of types. This patch adapts the
requests accordingly.
With this patch, Koha will still be compatible with Elasticsearch 7.x
but will no longer work with Elasticsearch 6.x
Since Elasticsearch 6.x is no longer maintained, this should not be a
problem.

https://www.elastic.co/guide/en/elasticsearch/reference/7.17/removal-of-types.html

Tested with Search::Elasticsearch 6.80 and 7.717

Test plan:
1. Install Elasticsearch 8
   (use docker image: docker.io/koha/elasticsearch-icu:8.x)
2. Change the elasticsearch server location in $KOHA_CONF
3. Run misc/search_tools/rebuild_elasticsearch.pl -r -b -v
   It should fail
4. Apply the patch
5. Run misc/search_tools/rebuild_elasticsearch.pl -r -b -v
   It should end with "Total XXX records indexed"
6. Try to search some biblios and verify that it works the same as
   before
