[nataliekwong]

Tell us about the documentation you'd like us to add or update.

We added support for Segments and Filters to the Google Analytics (Universal Analytics) connector (https://github.com/airbytehq/airbyte/pull/16920).

This should be added to our documentation for the connector so that users know it's supported.

If applicable, add links to the relevant docs that should be updated
