Raise KeyError instead of ArgumentError in Registry
to make use of did_you_mean gem.

The did_you_mean gem only supports NameError, NoMethodError
and KeyError. However, for NameError the message does also need
to match a certain format and we can not use a custom message
like 'Factory not registered ...'. Therefore using KeyError
is to only logical conclusion.

The did_you_mean gem makes use of the receiver attributes, but
in Ruby > 2.5 it is not possible to set the receiver and key attributes
on a KeyError (they are only set when the KeyError is raised in C).
We explored monkey patching KeyError for earlier versions of Ruby, but
it was a problematic solution.

Instead we can rescue the original KeyError, take the message from it,
which will already include the did_you_mean message, then customize
the message and re-raise a new KeyError with that customized message.
Starting in Ruby 2.6 this will not be necessary anymore
https://bugs.ruby-lang.org/issues/14313, so maybe we can get rid of it
for FactoryBot 6 or 7.

Fixes #992
