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:

<!-- Input -->
999999998. text

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

This fixes the addition space before + in CSS type() declaration. For example type(<number>+) was being converted into type(<number> +) which is invalid CSS and does not work.

/* Input */
div {
  border-radius: attr(br type(<length>+));
}

/* Prettier 3.9.4 */
div {
  border-radius: attr(br type(<length> +));
}

/* Prettier 3.9.5 */
div {
  border-radius: attr(br type(<length>+));
}

}

// Prettier 3.9.5
a {
  box-shadow+: 0 0 1px #000;
}
<!-- Input -->
[[Foo:Bar]]

<!-- Prettier 3.9.4 -->
[[Foo]]

<!-- Prettier 3.9.5 -->
[[Foo:Bar]]

}
