repocheck fails with "disallowed submodule url"

Summary

Repository check of (at least) one ancient, already archived repository fails here recently with

E, ... ERROR -- : ... Could not fsck repository: error in blob b5eb6db4a...: gitmodulesUrl: disallowed submodule url: https://XXXXXXXX,de/xxxxxxxxxx

(triggered probably by the , vs. . typo).

This bad commit happened before such a check was implemented and it is impossible to fix it in the repository.

It should be possible to ignore these errors during repository check.

Seen with 17.0 the first time.
