Fix auto guide generation on master (#284)

* prevent warning on user guide creation: current user from gh actions vs. owner: detected dubious ownership in repository at '/__w/moderncv/moderncv'

* manipulate conditions for tests besides the master branch!

* add debug output lines

* <automated> build of user guide

* revert debug outputs and manipulation of branches for tests

* Revert "<automated> build of user guide"
