IsSafeStringLiteralMulti returning false for windows (CRLF) newlines

[nyctef]

Hi! I've been investigating this library to see if we could use it and it looks pretty cool so far - thanks!

I think I might have found a bug, though. I'm trying to use TomlPropertyDisplayKind.StringLiteralMulti but it's not working as expected. I thing the issue might be in this line:

Tomlyn/src/Tomlyn/Helpers/TomlFormatHelper.cs

Line 230 in 477d573

if ((c == '\r' && i + 1 < text.Length && text[i + 1] == 'n') || c == '\n')

there's a 'n' that's probably supposed to be a '\n'.

Likely, PR welcome
