[FEATURE]: Return `changes/lastInsertRowid` as opposed to `void` when using Bun Sqlite driver

### Describe what you want

As of Bun 1.1.14 `db.insert` returns a result in the form:

```ts
{ changes: number, lastInsertRowid: number }
```

(see https://bun.sh/blog/bun-v1.1.14#track-changes-with-query-run-sql )

However Drizzle `db.insert()` returns void, causing the following TS error:
`Property 'lastInsertRowid' does not exist on type 'void'.` in the following example:

```ts
const result = db.insert(users).values(user).run();
console.log(result.lastInsertRowid);
```

A workaround would be:
```ts
const result = db.insert(users).values(user).run() as unknown as { changes: number; lastInsertRowid: number };
console.log(result.lastInsertRowid);
```

It would be great if the return value from the sqlite driver could be passed on so TypeScript understands it.
