Support TypeScript 5.0 (#​14391 by @​fisker, #​13819 by @​fisker, @​sosukesuzuki)

TypeScript 5.0 introduces two new syntactic features:

• const modifiers for type parameters
• export type * declarations

Add missing parentheses for decorator (#​14393 by @​fisker)

// Input
class Person {
  @​(myDecoratorArray[0])
  greet() {}
}

// Prettier 2.8.4
class Person {
  @​myDecoratorArray[0]
  greet() {}
}

// Prettier 2.8.5
class Person {
  @​(myDecoratorArray[0])
  greet() {}
}

Add parentheses for TypeofTypeAnnotation to improve readability (#​14458 by @​fisker)

// Input
type A = (typeof node.children)[];

// Prettier 2.8.4
type A = typeof node.children[];

// Prettier 2.8.5
type A = (typeof node.children)[];

Support max_line_length=off when parsing .editorconfig (#​14516 by @​josephfrazier)

If an .editorconfig file is in your project and it sets max_line_length=off for the file you're formatting,
it will be interpreted as a printWidth of Infinity rather than being ignored
(which previously resulted in the default printWidth of 80 being applied, if not overridden by Prettier-specific configuration).

<!-- Input -->
<div className='HelloWorld' title={`You are visitor number ${ num }`} onMouseOver={onMouseOver}/>

<!-- Prettier 2.8.4 -->
<div
  className="HelloWorld"
  title={`You are visitor number ${num}`}
  onMouseOver={onMouseOver}
/>;

<!-- Prettier 2.8.5 -->
<div className="HelloWorld" title={`You are visitor number ${num}`} onMouseOver={onMouseOver} />;
