Random::DEFAULT is deprecated on Ruby 3

[connorshea]

Describe the bug

Faker causes deprecation warnings on Ruby 3.

To Reproduce

Run code using Faker on Ruby 3 with deprecation warnings enabled (RUBYOPT='-W:deprecated') and see that you get a warning about Random::DEFAULT being deprecated:

/Users/connorshea/.rbenv/versions/3.0.0/lib/ruby/gems/3.0.0/gems/faker-2.15.1/lib/faker.rb:32: warning: constant Random::DEFAULT is deprecated

Can probably reproduce this with the gem's own test suite, I assume.

Expected behavior

No deprecation warning should be printed because we shouldn't use anything that's deprecated.

See the "Random" section of the NEWS.md file for 3.0.0 for more context and how to fix this warning: https://github.com/ruby/ruby/blob/v3_0_0/NEWS.md

Additional context

Ruby version: 3.0.0
Faker version: 2.15.1

This is the code:

faker/lib/faker.rb

Line 32 in a1ba45c

@random || Random::DEFAULT

I think we can just replace Random::DEFAULT with Random.new and it'll work fine?
