Rails/UnknownEnv support Rails.env.local? by default for Rails 7.1

[yahonda]

Is your feature request related to a problem? Please describe.

rails/rails#46786 has been merged to Rails main.
When this feature is released in Rails 7.1, I prefer Rails/UnknownEnv cop allows Rails.env.local? by default.

Describe the solution you'd like

Rails/UnknownEnv cop allows Rails.env.local? by default for Rails 7.1.

Describe alternatives you've considered

Update .rubocop.yml manually as rubocop/rubocop#4956 (comment) does.

Rails/UnknownEnv:
  Environments:
    - production
    - development
    - test
    - local

Additional context

It may be a little bit early to open this feature request because Rails 7.1 is not released.

Here are the steps to reproduce.

git clone https://github.com/yahonda/sampleapp.git
cd sampleapp
bundle
bundle exec rubocop

$ bundle exec rubocop
Inspecting 31 files

Offenses:

app/models/user.rb:2:16: C: Rails/UnknownEnv: Unknown environment local.
  if Rails.env.local?
               ^^^^^^

How Rails.env.local? works.

$ bin/rails c
Loading development environment (Rails 7.1.0.alpha)
irb(main):001:0> Rails.env.local?
=> true
irb(main):002:0> Rails.env
=> "development"
irb(main):003:0>

FYI

Rails.env.local? is a kind of syntax sugar for Rails.env.development? || Rails.env.test?

$ RAILS_ENV=test bin/rails c
Loading test environment (Rails 7.1.0.alpha)
irb(main):001:0> Rails.env.local?
=> true
irb(main):002:0> Rails.env
=> "test"
irb(main):003:0> exit

$ RAILS_ENV=production bin/rails c
Loading production environment (Rails 7.1.0.alpha)
irb(main):001:0> Rails.env.local?
=> false
irb(main):002:0> Rails.env
=> "production"
irb(main):003:0> exit
$
