### Description

Users may see the below log message under various circumstances,

> https://github.com/elastic/elasticsearch/blob/v8.3.3/server/src/main/java/org/elasticsearch/index/mapper/TextFieldMapper.java#L899-L906
> Text fields are not optimised for operations that require per-document field data like aggregations and sorting, so these operations are disabled by default. Please use a keyword field instead. Alternatively, set fielddata=true on [FIELD_NAME] in order to load field data by uninverting the inverted index. Note that this can use significant memory.

as people seem to have mentioned this message in [Elasticsearch](https://github.com/elastic/elasticsearch/issues?q=is%3Aissue+%22Text+fields+are+not+optimised+for+operations%22+), [Kibana](https://github.com/elastic/kibana/issues?q=is%3Aissue+%22Text+fields+are+not+optimised+for+operations%22+), and [Beats](https://github.com/elastic/beats/issues?q=is%3Aissue+%22Text+fields+are+not+optimised+for+operations%22+) GH issues as well as at [forums](https://discuss.elastic.co/search?q=%22Text%20fields%20are%20not%20optimised%20for%20operations%22).

I don't intend to suggest revise of this well-known message but want to propose an insertion of contextual information - i.e. field and index name to clarify where to start troubleshooting at a glance.

**Proposal**

If this proposal sounds reasonable, please let me know, and I will open PRs accordingly. Thanks.
