Markdown: Cap ordered list mark at 999,999,999 (#​19351 by @​tats-u)

CommonMark parsers only support ordered list item numbers up to 999,999,999.

With this change, Prettier now caps the ordered list item number at 999,999,999 to ensure that the output is correctly parsed as an ordered list by CommonMark parsers. Numbers larger than 999,999,999 are not parsed as list item numbers and are left unchanged in the output:

CSS: Prevent addition space in type() with + (#​19516 by @​bigandy)

}

TypeScript: Allow decorators to be used with declare on class fields (#​19492 by @​evoactivity)

Extensively used within the Ember ecosystem, decorators with declare on class fields will ignore the babel parser error and allow Prettier to format the code without breaking it.

  @&#8203;service declare server: ServerService;
}

// Prettier 3.9.1
// SyntaxError: Decorators can't be used with a declare field. (2:3)

//> 2 |   @&#8203;service declare server: ServerService;
