[nrf fromlist] doc: extensions: link-roles: missing module not critical

External projects building the documentation may not clone all modules, as
they have manifest filtering. Therefore, not having access to a module
should not produce a fatal documentation build error. Convert the error to
a debug log, so it is at least traced.
