PaginationParamsRequest ID params incorrectly typed as `string`

`PaginationParamsRequest` is typed as `string` when it should be typed as `int`.  This causes the request to fail with this error:

```
error: \"expected number for field \"watchers.id_gte\" but got number `0`\nexpected number for field \"watchers.id_gte.id_lte\" but got number `0`\""
```
