docs(commit): add multiline option questions content table

[ArneSchwerdt]

Description

I suggest to mention the multline support for input question in the documentation since it is already supported and a multiline description in the body is essential for good commits

Checklist

• Add test cases to all the changes you introduce
• Run ./scripts/format and ./scripts/test locally to ensure this change passes linter check and test
• Test the changes on the local machine manually
• Update the documentation for the changes

Expected behavior

Question type = input and option multiline = True, multiline input is possible

Steps to Test This Pull Request

• created .cz.yaml and added the option multiline: true to the question type: text and type: input
• in Allow multiline commit messages when using a custom .cz.toml #264 (comment) marcosdotme tested it in toml and reported it works

Additional context

Closes: #264
