Syntax highlighting breaks for templates with parenthesis

[MaryamZi]

Description

$title, when used as a default value of a parameter (therefore within parenthesis).

We might run into this often with with upcoming changes to use raw templates as default values for prompts.

Steps to Reproduce

isolated function fn(string c = string`
   - (AI in healthcare)?
`) returns int|error = external;


public function main() returns error? {
    string[] & readonly first = [];
}

When the closing parenthesis within the template is removed

isolated function fn(string c = string`
   - (AI in healthcare?
`) returns int|error = external;


public function main() returns error? {
    string[] & readonly first = [];
}
