Issue Description:

On https://docs.swift.org/swift-book/ReferenceManual/LexicalStructure.html#grammar_string-literal, the following lines make it seem as though extended delimiters are required for multiline strings:

multiline-string-literal-opening-delimiter → extended-string-literal-delimiter """
multiline-string-literal-closing-delimiter → """ extended-string-literal-delimiter

Shouldn't extended-string-literal-delimiter be optional, like with regular strings?

string-literal-opening-delimiter → extended-string-literal-delimiter opt "
string-literal-closing-delimiter → " extended-string-literal-delimiter opt
