Fix incorrect documentation about ifRestrictedRunInstead in NoParam variants

Corrected Variant Differences section:
- NoParam variants DO have ifRestrictedRunInstead parameter
- It's signature is void Function() instead of RunInsteadHandler<TParam>
- Previous doc incorrectly stated NoParam variants don't have this parameter

Verified against source code in command_it.dart lines 1196 and 1315.

 **NoParam variants:**
 - Function signature has **no parameter**: `Future<TResult> Function()` instead of `Future<TResult> Function(TParam)`
-- **No `ifRestrictedRunInstead` parameter** (since there's no param to pass to it)

 **NoResult variants:**
 - Function returns `void`: `Future<void> Function(TParam)` instead of `Future<TResult> Function(TParam)`
