Update terminologies

[JuanitoFatas]

Problem

These outdated terms could be offensive and harder to understand.

Description:

Update terminologies. Use permit, permitted, allowlist to replace existing ones where applicable.

Original motivation, other community efforts examples:

• [ci skip] change all instances of blacklist and whitelist to denylist… rails/rails#33681
• deserialize_jsonapi not found on controller graphiti-api/graphiti#10
• Finish converting whitelist and blacklist references rails/rails#33718
• Use friendlier terminology in YAML.safe_load ruby/psych#378
• Use friendlier terminology in rubysocket.h ruby/ruby#2008
• Use friendlier terminology in _leaf_helpers.erb ruby/ruby#2009
• Use permitted in line_length.rb rubocop/rubocop#6464
• Update friendlier terminology in Gem::SafeYAML ruby/rubygems#2463
• Introduce Request::ALLOWED_SCHEMES and deprecate existing constant rack/rack#1314
• Update terminology in http_status.rb rubocop/rubocop#6466
• Update terminology in rails/validation.rb rubocop/rubocop#6467
• Update terminology in BUILD_DETAIL.md rspec/rspec-core#2576
• Update terminology in BUILD_DETAIL.md rspec/rspec-expectations#1083
• Update terminology in BUILD_DETAIL.md rspec/rspec-mocks#1246
• Update terminology in BUILD_DETAIL.md rspec/rspec-support#356
• Use safelist(s), allowlist(s) where applicable flavorjones/loofah#158
• Use clearer terminologies pry/pry#1874
• Update terminology in test description from completion spec pry/pry#1875

This is a breaking change. We should bump to 2.0.0.
