Fix review line in default.xml as ssh is not supported by repo.

Fix review line in default.xml as ssh is not supported by repo.

A review= line cannot have ssh:// within repo, only http and https.

This can be fixed by using the https address with /gerrit/ at the end.
The ssh port will be queried then using  /gerrit/ssh_info from the server.
