Update telemetry docs to reflect Rudder removal

[esarafianou]

Summary

• Removes all references to pdat.matterlytics.com and RudderStack, which were fully removed from the server in MM-64486 (Sep 2025).
• Drops the now-defunct Deployment and server configuration data, Event data, and Playbooks telemetry sections — the Rudder batch/event pipeline they described no longer exists in the codebase.
• Updates the EnableDiagnostics setting description to accurately reflect that it now only gates Sentry error/crash reporting.
• Removes the dead VerboseDiagnostics config setting entry (LogSettings.VerboseDiagnostics / MM_LOGSETTINGS_VERBOSEDIAGNOSTICS), which has no implementation in the server.

📝 Walkthrough

Walkthrough

The telemetry docs now describe security update data without the CloudFront location item, and error reporting now states that server errors and panics are sent to Mattermost’s Sentry endpoint. The matching environment configuration entry was updated to use the same wording.

Changes

Layer / File(s)	Summary
Security update check section source/administration-guide/manage/telemetry.rst	The security update check heading and collected-data list were updated, including removal of the Amazon CloudFront location bullet.
