Remove the Zanata URL and checksum from translate.openstack.org. Due to
the latest change in puppet-zanata, this will upgrade it to version
3.7.3. Remove it entirely so that the checksum type can be updated in
puppet-zanata, and then it will be added back here to make sure
translate doesn't upgrade without us watching.
