[GitlabIssueBridge] Fix example values for MR

These values are used for testing and PR artifacts, but
https://gitlab.com/fdroid/fdroidclient currently has no MR !2099,
leading to a HTTP 404 error. This just uses issue RSS-Bridge#1 and MR !1.

The epics are repository-independent, so no example values can fit both
issue/MR and epic templates.
