In elastic#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.

In #30209 we deprecated the camel case `nGram` filter name in favour of `ngram` and did the same for `edgeNGram` and `edge_ngram` and we are removing those names in 8.0. This change disallows using the deprecated names for new indices created in 7.0 by throwing an error if these filters are used. Relates to #38911

In #30209 we deprecated the camel case
nGramtoken filter in favour ofngramanddeprecated
edgeNGramin favour ofedge_ngram. Using these names has been deprecatedsince 6.4, issuing deprecation warnings on new indices since then. In addition to remove the filter
in 8.0 completely (see ##38911) we should not allow index creation using these filter names
starting with 8.0. This PR adds throwing an IAE when this filter name is used in indices created from
7.0 on.
