Bump acme-client version to 2.0.5
Let's Encrypt dropped support of unauthenticated GET requests to their staging API. Older version of acme-client
gem used it, and hence our LE integration broke. This one bumps acme-client
to a version that uses POST-as-GET requests, which is the recommended method currently.
Closes #4900 (closed)
