`RSpec/ExampleWording` unintentionally removes escapes

[r7kamura]

I noticed that it autocorrects as follows, which causes syntax error:

# before
it 'should return foo\'s bar' do
end

# after
it 'returns foo's bar' do
end

This can be confirmed by the following test code.

diff --git a/spec/rubocop/cop/rspec/example_wording_spec.rb b/spec/rubocop/cop/rspec/example_wording_spec.rb

Since this cop supports not only str but also dstr, it would be difficult to simply fix it with String#inspect 🤔

We’ve been discussing this in #1189 and closed it as won’t fix.

Would it be possible to at least fix the str cases? Would you want to give the fix a try, @r7kamura ?

Sorry, I didn't realize there was already an issue in the past.

I created a pull request to work on this issue:
