BulkWriter: DEADLINE_EXCEEDED error when deleting documents in single collection

When using `BulkWriter` to delete 5,000 documents simultaneously from a single collection, I’m getting the following error:
````
4 DEADLINE_EXCEEDED: Deadline exceeded after 72.021s,metadata filters: 0.001s,remote_addr=173.194.64.95:443
````

Despite the BulkWriter returning the deadline exceeded error, all the documents are eventually deleted.

Additionally, I’ve noticed that the default [error handler function](https://github.com/googleapis/nodejs-firestore/blob/main/dev/src/bulk-writer.ts#L504) in BulkWriter doesn’t retry the DEADLINE_EXCEEDED error ([config](https://github.com/googleapis/nodejs-firestore/blob/main/dev/src/v1/firestore_client_config.json#L110)). However, this error can be retried for single deletion operations [according to the configuration](https://github.com/googleapis/nodejs-firestore/blob/main/dev/src/v1/firestore_client_config.json#L55C32-L55C89).
