A tag is required to reuse Elasticsearch breaking changes in the Stack
Guide. To display properly, the breaking changes must use external
links rather than xrefs.
This PR correctly places those tags for reuse. It also replaces
several xrefs with external links for reuse.
* Removes docs and references for the following `geo_shape` mapping parameters:
* `tree`
* `tree_levels`
* `strategy`
* `distance_error_pct`
* Updates a related breaking change.

Follow up to #62623, this commit removes support in 8x for index-time boosts.
There is no longer a boost field on MappedFieldType. Indexes created in 8x
and after will throw exceptions if a boost parameter is included in mappings,
and indexes created in 7x will emit warnings.
We removed index-time boosting back in 5x, and we no longer document the 'boost'
parameter on any of our mapping types. However, it is still possible to define an
index-time boost on a field mapper for a surprisingly large number of field types, and
they even have an effect (sometimes, on some queries).
As a first step in finally removing all traces of index time boosting, this comment emits
a deprecation warning whenever a boost parameter is found on a mapping definition.
After deprecating the `enabled` setting for `_field_names`starting with 7.5,
this change disallows the setting on new indices in 8.0. The setting continues
to work for indices created in 7.x where we continue emitting a deprecation warning.
Relates to #42854
The removal of the "nGram" and "edgeNGram" token filter was filed in a new
migrate_8_0/mappings.asciidoc document but it should better be in an
analysis.asciidoc section and file.
In #30209 we deprecated the camel case `nGram` filter name in favour of `ngram` and
did the same for `edgeNGram` and `edge_ngram`. Using these names has been deprecated
since 6.4 and is issuing deprecation warnings since then.
I think we can remove these filters in 8.0. In a backport of this PR I would change what was a
dreprecation warning from 6.4. to an error starting with new indices created in 7.0.
