The srand() seeding behaviour appears to have changed in Ruby 3.

Here is a quick test which shows the differences in behaviour between difference Ruby versions: https://jdoodle.com/ia/BEL

The 1<<32 ( or 2**32) seed in Ruby 2.x versions was equivalent to the 0 seed of the Python reference.

In Ruby 3, srand(1<<32) is equivalent to the srand(0) -- which breaks the seeding. Previously they were different.

Random.new(0).rand == Random.new(1<<32).rand

was false for Ruby 2.x. Now true for Ruby 3.x

I don't know what seed will give the expected first result of 0.8444218515250481 in Ruby 3.x
