Multiline Description support for params

[SpaskeISO]

Is your feature request related to a problem? Please describe.
I am trying to add a json exaple to a param description but i have no way of adding new lines since the ``` json ``` in swagger UI doesn't support <br> or \n.

Describe the solution you'd like
Adding a field like // @param.description for descriptions

Describe alternatives you've considered
Search for // @description annotation after params for multiline comments
Make generator look for \n in the // @param description and to add a new line every time it finds one in the description section of the parameter
