The `WithReplicaSet` option configures the MongoDB container to run a single-node replica set named "rs". The container will wait until the replica set is ready.

Implementing a
WithReplicaSetfunction to configure the container to run with a default single-node replica set named "rs". This function appends "--replSet rs" toreq.Cmdto initialize MongoDB in preparation to receive a replica set. Additionally, after execution, it initializes the replica set using "rs.initiate()", configuring the current host as the PRIMARY.Why is it important?
I've been utilizing testcontainers to test my service environment, which necessitates a replica set to execute transactions. As I've developed this functionality for internal use, I believe it would be beneficial to others as well.
