* Adapt number types in ast
Since mypy 0.990 type promotions was limited.
This means that complex is not longer promoted to int/float, therefore
we should adapt the types to list all possible types

The following patterns still break mypy:
1. `type[]` at top level fails
2. `tuple[T1, T2]` at top level fails (but `tuple[T1, ...]` is fine)
3. `T1 | Callable[..., T2 | T3]` fails, but only <=3.9
This PR cleans up usage of `Union` and `Optional` outside these patterns.
