Take Composer runtime API in account when sorting requirements

see contao/contao#3935 (comment)

We should probably adjust these:

monorepo-tools/src/Command/ComposerJsonCommand.php

Lines 394 to 421 in 14d48ea

	uksort(
	$requires,
	static function ($a, $b) {
	if ('php' === $a) {
	return -1;
	}
	if ('php' === $b) {
	return 1;
	}
	if (
	(0 === strncmp($a, 'ext-', 4) && 0 !== strncmp($b, 'ext-', 4))
	|| (0 === strncmp($a, 'lib-', 4) && 0 !== strncmp($b, 'lib-', 4))
	) {
	return -1;
	}
	if (
	(0 !== strncmp($a, 'ext-', 4) && 0 === strncmp($b, 'ext-', 4))
	|| (0 !== strncmp($a, 'lib-', 4) && 0 === strncmp($b, 'lib-', 4))
	) {
	return 1;
	}
	return strcmp($a, $b);
	}
	);
