Per #17639 (comment), xpack.reporting.csv.enablePanelActionDownload: true is an experimental feature starting in 7.3.0. However, even in 7.3.0 documentation, we have not specified this option as experimental.

1. Is this feature still experimental today?
2. If so, it will be helpful to add the experimental tag to the documentation for 7.3 to 7.x versions.

thx!
