Created by: developersteve

Description

Ruby generation breaking if 'in' is in any path multi line description, only seems to be ruby that has an issue language wise.

openapi-generator version

3.2.0

OpenAPI declaration file content or url

          description: |
            A JSON or XML payload containing the recipient's phone number and MMS message.
            The recipient number should be in the format '04xxxxxxxx' where x is a digit.

Steps to reproduce

Generate ruby lib then try to use it, for any description text on a new line the text wont be parsed

Suggest a fix/enhancement

Allow for multi line text to be parsed (check for CR)
