[Internal]: Need to update Filebeat input filestream doc, rephrase note

### Description

In versions 8.18 and 8.19, a warning/note in the Filebeat filestream input documentation contains incorrect text (other versions were not checked by the reporter).

**Location:** https://www.elastic.co/guide/en/beats/filebeat/8.18/filebeat-input-filestream.html#filestream-file-identity → `filestream-file-identity` section

**Current (incorrect) text:**
> "Any unsupported change in file_identity methods between duplicated events in the output."

**Expected (correct) text:**
> "Any unsupported change in file_identity methods between runs may result in duplicated events in the output."

The phrase "between runs may result in" is missing, making the sentence incomplete and misleading.

In 8.18 and 8.19 versions this warning/note message is NOT correct (I didn't check previous ones)
- Go to https://www.elastic.co/guide/en/beats/filebeat/8.18/filebeat-input-filestream.html#filestream-file-identity
- Look for "Any unsupported change in file_identity methods between duplicated events in the output."

**Type:** documentation

**Section check:**
- ✅ What's incorrect and where: identified (URL, anchor, current text, and expected text all provided)

**Ambiguity / scope notes:**
- Affected versions listed as 8.18 and 8.19; author notes other versions were not checked — assignee should verify coverage

**Cross-references:**
- https://www.elastic.co/guide/en/beats/filebeat/8.18/filebeat-input-filestream.html#filestream-file-identity — well-formed URL; content not independently verified

**Next step:** Rewritten above

Open the Filebeat filestream documentation at the provided 8.18 URL and navigate to the filestream-file-identity section. Find the quoted incorrect note, replace it with the expected wording, and check whether the same text appears in the 8.19 documentation as well. Done means the sentence is complete and accurate in the affected versions.
