Problem description

Hello,

Since ES8.0 field_masking_span is deprecated in favor of span_field_masking. Ref: https://github.com/elastic/elasticsearch/pull/74718/files

This change is not reflected to elasticsearch-java client causing exception on ES: deprecated fields not supported here but got [field_masking_span] which has been replaced with [span_field_masking]

I've made this PR to propose a fix. (I signed the agreement right after creating the PR making the validation failed - sorry about that :) )

Thanks for your help
