fix: canonicalization of non-standard OfNat.ofNat terms (#9481) 
This PR fixes a kernel type mismatch that occurs when using `grind` on
goals containing non-standard `OfNat.ofNat` terms. For example, in issue
#9477, the `0` in the theorem `range_lower` has the form:
```lean
(@OfNat.ofNat
  (Std.PRange.Bound (Std.PRange.RangeShape.lower (Std.PRange.RangeShape.mk Std.PRange.BoundShape.closed Std.PRange.BoundShape.open)) Nat)
  (nat_lit 0)
  (instOfNatNat (nat_lit 0)))
```
instead of the more standard form:
```lean
(@OfNat.ofNat
  Nat
  (nat_lit 0)
  (instOfNatNat (nat_lit 0)))
```

Closes #9477
