This newer version actually restores APIKEY authentication, but we
already converted to oauth2.0 so we don't revert. Otherwise it seems
like there are a number of small fixes. Full change log here:
https://github.com/ether/etherpad-lite/blob/v2.1.1/CHANGELOG.md
In this change we resync configuration template files which results in a
few small updates. We also realign the dockerfile with upstream which
also results in a few small updates one of which is bumping the nodejs
version to 22 from 20.
