TypeScript `as const` is not considered a type

I wanted to delete a bunch of `as const` (after updating to TypeScript 5.0 and adding `const` to my generics) in some statements like

```ts
foo(Bar, {
  action: 'baz' as const,
});

foo(Bar, {
  action: 'baz',
} as const);
```

but there's no convenient way to target the `as const`.
