Pattern `[".."]` inside multi-line docstring

Hi 👋🏻 The parser fails on the following code ``` namespace App { @doc(""" some ["doc"] """) @route("/route") @post op route(): Foo; } ``` with the problematic part of the AST being ``` (decorator ; [1, 2] - [4, 18] name: (identifier_or_member_expression ; [1, 3] - [1, 6] (identifier ; [1, 3] - [1, 6] (plain_identifier))) ; [1, 3] - [1, 6] (decorator_arguments ; [1, 6] - [4, 18] (ERROR ; [1, 7] - [4, 9] (triple_quoted_string_fragment) ; [1, 10] - [2, 10] (expression_list ; [2, 10] - [2, 15] (quoted_string_literal ; [2, 10] - [2, 15] (quoted_string_fragment))) ; [2, 11] - [2, 14] (triple_quoted_string_fragment)) ; [3, 7] - [4, 9] (expression_list ; [4, 9] - [4, 17] (quoted_string_literal ; [4, 9] - [4, 17] (quoted_string_fragment))))) ``` Removing any of `["` or `"]` fixes parsing.
