[DRE-maint] Bug#1006026: ruby-axiom-types: FTBFS: ERROR: Test "ruby3.0" failed: ArgumentError: Cannot proxy frozen objects, rspec-mocks relies on proxies for method stubbing and expectations.

[Antonio Terceiro]

Control: retitle -1 ruby-axiom-types: FTBFS randomly: ArgumentError: Cannot proxy frozen objects, rspec-mocks relies on proxies for method stubbing and expectations.

I tried this locally and couldn't reproduce twice in row, first on my
main system, then with sbuild. I then tried 10 times in a row, and got a
60% failure rate. Tried again 20 times, then 55% failure rate.

I tried debugging this with the upstream sources from git and
ruby-standalone + bundler, but the upstream tree has broken dependencies
and I lost my patience.
