James Rodewig 095c34359f [DOCS] Note limitations of max_gram parm in edge_ngram tokenizer for index analyzers (#49007)
The `edge_ngram` tokenizer limits tokens to the `max_gram` character
length. Autocomplete searches for terms longer than this limit return
no results.

To prevent this, you can use the `truncate` token filter to truncate
tokens to the `max_gram` character length. However, this could return irrelevant results.

This commit adds some advisory text to make users aware of this limitation and outline the tradeoffs for each approach.

Closes #48956.
