Fix all uses of `/dist/` in type imports

Per Andrew Branch, these are bad and breaking things:

```ts

import type { Api } from '@reduxjs/toolkit/dist/query/apiTypes'

import type {
  QuerySubState,
  SubscriptionOptions,
  QueryKeys,
  RootState,
} from '@reduxjs/toolkit/dist/query/core/apiState'

// etc
```

They should just import from the packages instead, like `@reduxjs/toolkit/query`.
