Module.parent: NoMethodError for String#squish

[sshaw]

Deprecation warning uses it. It lives in active_support/core_ext/string/filters.rb but it's never required.

Steps to reproduce

~/code/ruby/class2 >ruby -ractive_support/version -e'p ActiveSupport.version'
#<Gem::Version "6.0.2.2">

---

~/code/ruby/class2 >ruby -ractive_support/core_ext/module -e'Module.new.parent_name'
Traceback (most recent call last):
	1: from -e:1:in `<main>'
/Users/sshaw/.rvm/gems/ruby-2.5.2/gems/activesupport-6.0.2.2/lib/active_support/core_ext/module/introspection.rb:20:in `parent_name': undefined method `squish' for #<String:0x00007fbd819c8510> (NoMethodError)

Expected behavior

Deprication warning

Actual behavior

NoMethodError

System configuration

Rails version: NA

Ruby version: 2.5.2
