Create a type that changes the type of the given keys.

Use-cases:
|
|
- Creating variations of a base model.
|
|
- Fixing incorrect external types.
|

|
|
@see `Merge` if you need to change multiple properties to different types.

|
|
@example
|
|
```
|
|
import type {SetFieldType} from 'type-fest';
|

type MyModel = {

// updatedAt?: string;
