fix a typo: 3nd -> 3rd

[batkiz]

btw, how could I add a command option's values completion with CommandInfo class? just like

$options['audit'] = [ordered] @{
	'--groups'  = @(
		'devDependencies',
		'dependencies',
		'optionalDependencies'
	);
}

in https://github.com/PowerShell-Completion/yarn-completion/blob/aa6fa779a02b5ad2cf163632eedf0200c9a9bbf1/src/options/audit.ps1#L6

This is correct ordinal in invariant English.
