Ciro Spaciari ff6af0e2f7 fix(Bun.SQL) delay postgres promise resolve for prepared statements (#22090)
### What does this PR do?
fixes https://github.com/oven-sh/bun/issues/21945
### How did you verify your code works?
Run the code bellow and will be way harder the encounter the same
problem (I got it 1 times after 10 tries the same effect as Bun.sleep
mentioned before)

```ts
const sql = new Bun.SQL("postgres://localhost");
using conn1 = await sql.reserve();
using conn2 = await sql.reserve();

await sql`DROP TABLE IF EXISTS test1`;
await sql`CREATE TABLE IF NOT EXISTS test1 (
id INTEGER PRIMARY KEY GENERATED ALWAYS AS IDENTITY,
uuid UUID NOT NULL
)`;
await sql`INSERT INTO test1 (uuid) VALUES (gen_random_uuid())`;
type Row = {
  id: number;
  uuid: string;
};

for (let i = 0; i < 100_000; i++) {
  const [original]: Array<Row> = await conn1`SELECT id, uuid FROM test1 LIMIT 1`;

  const [updated]: Array<Row> =
    await conn1`UPDATE test1 SET uuid = gen_random_uuid() WHERE id = ${original.id} RETURNING id, uuid`;

  const [retrieved]: Array<Row> = await conn2`SELECT id, uuid FROM test1 WHERE id = ${original.id}`;

  if (retrieved.uuid !== updated.uuid) {
    console.log("Expected retrieved and updated to match", retrieved, updated, i);
    break;
  }
}

```
