Allow `registerOTel` to pass different logRecordProcessors

[JerryLikeCoding]

This is the urgent issue for compatibility for the typing.

Issue: Currently the registerOTel() only allow to pass the type LogRecordProcessor. But the opentelemetry library has more specific types (eg. BatchLogRecordProcessor). And it is causing the type checking issues.

Target: We should update the registerOTel and allow it to pass more specific types.

Reproduce: The below is the code:

import {
  BatchLogRecordProcessor,
  LogRecordExporter,
} from '@opentelemetry/sdk-logs';
import { registerOTel } from '@vercel/otel';

const logRecordProcessor = new BatchLogRecordProcessor(
  logExporter as LogRecordExporter
);

registerOTel({
  serviceName, // use your own service name
  traceExporter, // use your own trace exporter
  logRecordProcessor,
});

And then we can see the error:
