Add support for multiline strings.

[QrackyDev]

I found out that multiline strings where not supported and breaks the loader generation. I personally like multiline comments a lot because of readability and it being easier to use. Could this be added?

Thanks for your consideration!

Thanks for the issue.

Colud you share an example YAML snippet or code that uses multliline strings?

Here is an example:

@Comment("""
    The amount of time to pass until a new update check occurs.
    Default: 1h
""")

The code snippet above generates the following code:

setComment(configuration, "${parentPath}updaterDelay", listOf("
                The amount of time to pass until a new update check occurs.
                Default: 1h
            "))
  }
