Fix `Dry::Inflector#constantize` to not inherit constants from sibling namespaces

[jodosha]

module Foo
  module Bar
    VERSION = "0.1.0"
  end

  module Baz
  end
end

module Test
end

module Check
end

inflector = Dry::Inflector.new

# BEFORE
inflector.constantize("Foo::Baz::VERSION") # => VERSION
inflector.constantize("Test::Check") # => Check

# AFTER
inflector.constantize("Foo::Baz::VERSION") # => raises NameError
inflector.constantize("Test::Check") # => raises NameError

CHANGELOG.md files are automatically generated from changelog.yml and we should have a banner about that... /cc @solnic

@flash-gordon what kind of a banner?

[flash-gordon]

@solnic "# DO NOT EDIT. THIS FILE IS AUTOMATICALLY GENERATED" kind of banner :)

[solnic]

@flash-gordon ah yeah, totally. I'll add it then!

[jodosha]

@flash-gordon My apologize, I didn't remember about that. :/

I wonder if we could configure git/github so that pushing certain files is only allowed by dry-bot 🤔
