chore: increase priority of defaultInstance for heterogeneous operators

Browse source 
@Kha The motivation is to allow users to define default instances such as
```lean
@[defaultInstance 1]
instance : OfScientific Real where
  ...
```
Then, numerals such as `1.2` and `3.4e10` will be `Real` by default instead of `Float`.
