Updates MailRoom version to 0.0.14

Release-tools wrongly restored the version to 0.0.9 on 3c537e10 when it was already upgraded on ea56bbd4.

Release-tools can't handle the divergence between GitLab and the Charts, so we're restoring mailroom to the correct version.

Bug in release tools is fixed by gitlab-org/release-tools!1592 (merged)
