Grok filter match_all option in parser syntax The Google SecOps parser syntax is updated to support the match_all option

## Feature Feature **Grok filter match\_all option in parser syntax** The Google SecOps parser syntax is updated to support the `match_all` option within the Grok filter. This allows parsers to extract all non-overlapping pattern occurrences within a field, rather than returning only the first match. For more information, see [Parser syntax reference](https://cloud.google.com/chronicle/docs/reference/parser-syntax#grok%5Fmatch%5Fall%5Foption).
