Appeasing Rubocop as it sneaks some changes in (#16085)
I was working on another branch and as part of my commit, Rubocop
removed a validation (but not the spec that asserted the validation).

Below is the "non-updating" rubocop offense on the other branch.

```shell
❯ rubocop ./app/models/notification_subscription.rb
Inspecting 1 file
C

Offenses:

app/models/notification_subscription.rb:13:29: C: [Correctable]
Rails/RedundantPresenceValidationOnBelongsTo: Remove explicit presence
validation for notifiable_id.
  validates :notifiable_id, presence: true
                            ^^^^^^^^^^^^^^

1 file inspected, 1 offense detected, 1 offense auto-correctable
```

To remediate, I ran:

```shell
> rubocop --only "Rails/RedundantPresenceValidationOnBelongsTo" \
  --auto-correct
```

This resolved the `app/models`.  Then did some regex magic and removed
the assertions from `spec/models`.

For Forem folks, I wrote a [forem.team post][1] discuss if this is how
we want to proceed.
