Improve LoggingParameterTree error message

Feature request

What does this feature / why does DuMux need it: My proposal is to include the group prefix if a parameter with group prefix could not be found

Which issue does this feature fix (if any) Users no longer have to check in which parameter group they forgot to define a parameter or misspelled it. Sometimes you have multiple parameters with the same name in different groups, e.g. multi-domain problems

Anything else we need to know?: I propose to replace DUNE_THROW(Dumux::ParameterException, "Key " << key << " not found in the parameter tree"); in https://git.iws.uni-stuttgart.de/dumux-repositories/dumux/-/blob/7e8c2744b2b69db3357390970748c8cd92dc6b21/dumux/common/loggingparametertree.hh#L488 with DUNE_THROW(Dumux::ParameterException, "Key " << key << " not found in the parameter tree with group prefix " << groupPrefix);
