[text-auditor] Fix duplicated-word typos and one awkward CLI help phrase in user-facing text

[github-actions]

Text Improvements

The following user-facing text issues were found in the repository. Each is a low-effort fix.

1. Duplicate word in Filebeat container input docs

File: docs/reference/filebeat/filebeat-input-container.md (line 15)
Current text: Please use the the [\filestream`](/reference/filebeat/filebeat-input-filestream.md) input... **Suggested fix:**Please use the `filestream` input... **Why:** Clear typo (the the`) in user-facing documentation.

2. Duplicate word in Filebeat log input docs

File: docs/reference/filebeat/filebeat-input-log.md (line 15)
Current text: Please use the the [\filestream`](/reference/filebeat/filebeat-input-filestream.md) input... **Suggested fix:**Please use the `filestream` input... **Why:** Clear typo (the the`) in user-facing documentation.

3. Duplicate words in HTTP endpoint input docs

File: docs/reference/filebeat/filebeat-input-http_endpoint.md (line 13)
Current text: ...expression that converts the the JSON body...
Suggested fix: ...expression that converts the JSON body...
Why: Clear grammar typo (the the) in user-facing documentation.

4. Duplicate words in exported fields docs

File: docs/reference/metricbeat/exported-fields-system.md (line 472)
Current text: The total number of of milliseconds spent doing I/Os.
Suggested fix: The total number of milliseconds spent doing I/Os.
Why: Clear typo (of of) in user-facing exported fields text.

5. Inconsistent capitalization in fatal error output

File: libbeat/cmd/export/template.go (line 52), libbeat/cmd/export/ilm_policy.go (line 50)
Current text: error creating file handler: %s
Suggested fix: Error creating file handler: %s
Why: User-facing fatal errors in same command surface are otherwise capitalized (Error exporting ...), making this an unambiguous consistency fix.

6. Awkward CLI help phrase

File: libbeat/cmd/completion.go (line 32)
Current text: Output shell completion code for the specified shell (bash and zsh only by the moment)
Suggested fix: Output shell completion code for the specified shell (bash and zsh only for now)
Why: User-facing help text uses unidiomatic phrasing; correction is clear and low-effort.

Suggested Actions

• Remove duplicated words in docs/reference/filebeat/filebeat-input-container.md and docs/reference/filebeat/filebeat-input-log.md.
• Remove duplicated words in docs/reference/filebeat/filebeat-input-http_endpoint.md and docs/reference/metricbeat/exported-fields-system.md.
• Capitalize error creating file handler in both export command files for consistency.
• Replace by the moment with for now in CLI completion help text.
