ruby 3.3.0 'incompatible marshal file format` errors

[mattlindsey]

Four of the tests fail in ruby 3.3.0 (although they work in 3.2.2) with an incompatible marshal file format error, even after updating gem dependencies:

Finished in 5.32 seconds (files took 0.04708 seconds to load)
25 examples, 4 failures

Failed examples:

rspec ./spec/safe_ruby_spec.rb:5 # SafeRuby#eval allows basic operations
rspec ./spec/safe_ruby_spec.rb:10 # SafeRuby#eval returns correct object
rspec ./spec/safe_ruby_spec.rb:46 # SafeRuby#eval options timeout defaults to a 5 second timeout
rspec ./spec/safe_ruby_spec.rb:53 # SafeRuby#eval options timeout allows custom timeout

Here is the first one:

  1) SafeRuby#eval allows basic operations
     Failure/Error: raise data
