Exclude any_approver rule from being marked as invalid

What does this MR do and why?

This MR excludes any_approver rule from being marked as invalid. It's a fix for issues described in #408161 (closed) and unblocks frontend changes from !117423 (merged) that were reverted by !118140 (merged)

Explanation of the fix:

• any_approver rules have different approved? conditions - they don't get automatically approved when they are invalid compared to other rules
• they are skipped from invalid_approvers_rules

How to set up and validate locally

1. Create a project
2. Under Preferences -> Merge requests, set Approvals required for All eligible users to 1
3. Open an MR
4. Use GraphiQL to query invalid. It should be false.

   {
     project(fullPath: "<project-path>") {
       id
       mergeRequest(iid: "<MR-iid>") {
         id
         approvalState {
           invalidApproversRules {
             id
           }
           rules {
             id
             invalid
           }
         }
       }
     }
   }
