[misilot]

Describe the bug I am applying

      EP__PLUGIN__ep_google_analytics__gaCode: G-NLVFX369BM
      EP__PLUGIN__ep_matomo__matomoSiteId: 43
      EP__PLUGIN__ep_matomo__matomoHostname: webanalytics.lib.k-state.edu

or

      EP__ep_google_analytics__gaCode: G-ffasdfadsf
      EP__ep_matomo__matomoSiteId: 43
      EP__ep_matomo__matomoHostname: servername

since the docoumentation isn't clear https://github.com/ether/etherpad-lite/blob/develop/doc/docker.md?plain=1#L223 or is it https://github.com/ether/etherpad-lite/blob/develop/doc/docker.md?plain=1#L237

To Reproduce Steps to reproduce the behavior:

1. Add env variables
2. login to admin panel, check settings, see nothing for matomo or google analytics present.

Expected behavior Should see variables in the settings, so they can be used.
