[Fix #8843] Fix invalid Lint/AmbiguousRegexpLiteral autocorrect when the original node had internal parentheses

[dvandersluis]

This previously used Util#add_parentheses to do correction, but this does not handle send nodes properly, so I changed it to just edit the node in place.

Fixes #8843.

Thanks for the patch. However, this solution causes incompatibility auto-correction when using method chain.
I opened a PR #8847 that includes a solution to use case of method chain. It seems that we tried to resolve the issue at almost the same timing 😅

@koic great! I'll close this one 😄

@dvandersluis I'm sorry about it. Thank you for your activity!

@koic no worries! I’ll keep trying to find more to fix and hopefully we’ll avoid conflicts 😁
