Minor: Properly require active_support

[ylecuyer]

I wanted to give a try at #99 so I ran `mrsk init --bundle' and pointed the gem at this PR
In the same Gemfile I'm running rails latest and got hit by this error:

$ bundle exec mrsk version
bundler: failed to load command: mrsk (/home/ylecuyer/.rbenv/versions/3.2.1/lib/ruby/gems/3.2.0/bin/mrsk)

Afaiu from the doc https://guides.rubyonrails.org/active_support_core_extensions.html we first need to require active_support before requiring extensions one by one so I simply added the require and it now works properly with latest rails version.

$ bundle info rails
