Add support for reviewer changes in merge requests

The merge request event webhook is called for reviwers updates, however this is ignored by the GitlabChanges class. Therefore these updates are not forwarded to Matrix. By adding the reviewers section to both the GitlabChanges and to the issue_update template (which is used for merge request updates) the bot reports about changes in reviewers.
