Reinstate params in rest api specs (#52544)

This commit reinstates the following params in the rest specs:

1. "analyzer" in delete_by_query
2. "ccs_minimize_roundtrips" in msearch_template
3. "ccs_minimize_roundtrips" in search_template

All appear to be valid options that seem to have been inadvertantly removed
between 7.3 and 7.4.

Fixes elastic/elasticsearch#47768
