Add fuzzy filter logic to filter expressions

https://www.elastic.co/guide/en/elasticsearch/reference/8.12/query-dsl-query-string-query.html#query-string-fuzziness

we should implement this feature in favor of multiline regex support to address the same use cases.
multiline regex would be to expensive during prozessing logs.
this could be a simple string lookup in a json document?

Start with the linked Elasticsearch query-string fuzziness documentation and locate the existing filter-expression handling in Logprep. Determine the intended fuzzy matching behavior and how it should replace multiline regex use, then identify suitable tests or examples for JSON log documents. Done means the behavior and performance expectations are specified and implemented without the proposed expensive multiline regex processing.
