Remove new line from translatable string

Due to our poor mans XML concatenation new lines are not kept and cause invalid XML. See https://github.com/nextcloud/docker-ci/pull/280/files#diff-9d28cba068f86de5b086c8b5e7ba5e44df1f4d5d299421e2bf5eb168551af078R68 for the XML concatenation. THis is a quick fix and better should be handled by just properly parse and combine the XML.
