Update Etherpad to v2.2.5

After the 2.2.4 release we upgraded to a development commit between
2.2.4 and the future (at that time non existant) 2.2.5 release to fix
integration between meetpad and etherpad. Now there is a proper 2.2.5
and we should update to get off the dev commit.

This release fixes a number of bugs, updates dependencies, and adds
proper swagger documentation for the API. The "complete" changelog can
be seen here:
  https://github.com/ether/etherpad-lite/blob/v2.2.5/CHANGELOG.md

Note that I don't believe the API has changed they are merely
documenting it properly using swagger. Our testing should confirm.
To expose the new swagger documentation we do add /api-docs/ and
/api-docs.json to our proxy exclusion list.

We also update our settings.json files to sync with upstream. This pulls
in a new `updateServer` key value pair to set the location that should
be checked by etherpad to determine if there is a newer version
available. I believe this behavior has existing for years they are just
now making it a bit more configurable. Unfortunately the way this value
is used I think we will do a local file lookup if we set the value to
"". I've stuck with the default since this shouldn't be a regression and
we can try to disable it later.
