### What did you see?

HAproxy logs are not parsed correctly and dropped.

Problem is that the [grok patterns](https://github.com/elastic/integrations/blob/ea03f0086f7a3c709861ef03f1fb957387bad197/packages/pfsense/data_stream/log/elasticsearch/ingest_pipeline/haproxy.yml#L6) contain multiple instances of double spaces instead of single spaces between words, and the patters will never match.


Spaces seems to correlate with line breaks in the yaml file with pipeline definitions.

### What did you expect to see?

HAproxy logs.

### Anything else?
