Add support for custom queue events

Is your feature request related to a problem? Please describe it

Currently I have to implement the new custom queue functionality by hand with something hacky like the following

const queueEvents = new QueueEventsPro(QUEUES.EVENTS_QUEUE, {
    connection: this.connection,
});
await queueEvents.waitUntilReady();

for (const event of Object.values(EventType)) {
  queueEvents.on(event as any, async (job) => {
    await this.processEvent(job);
  });
}

Describe the solution you'd like

Custom Queue Events were added last month in taskforcesh/bullmq#2844, however there are no NestJS decorators/classes added for it yet.

Teachability, documentation, adoption, migration strategy

No response

What is the motivation / use case for changing the behavior?

Being able to emit and process real-time distributed events.

Hey Kamil! Unfortunately this was just for a PoC that we won't be moving forward with, but I couldn't find anything online about the presence/lack of it in nestjs so wanted to add a note about it.
