fix: increase replicas for load balancing

- Change the number of replicas from 1 to 3 in the
  deployment configuration.
- This adjustment aims to improve load balancing and
  availability of the application.

Increasing the replicas allows the application to handle
more traffic and provides redundancy in case of failures.
