runtime(doc): wrong {str} length limit in matchfuzzy() docs

runtime(doc): wrong {str} length limit in matchfuzzy() docs

Problem: docs say {str} is capped at 256 and longer returns an empty list.
Solution: it's 1024, and {str} plus each candidate are just truncated to
that, not rejected; fix the text.

closes: #20453

+ {str} and of each item in {list} are used for matching;
+ characters beyond that are ignored.

When {str} has multiple words each separated by white space,
then the list of strings that have all the words is returned.

If there are no matching strings or there is an error, then an
- empty list is returned. If length of {str} is greater than
- 256, then returns an empty list.
+ empty list is returned.

When {limit} is given, matchfuzzy() will find up to this
number of matches in {list} and return them in sorted order.
