DRIVERS-3128 test secondary with IPv6 literal in SDAM

[kevinAlbs]

Summary

Add regression test for the bug identified in this comment of HELP-68823.

Motivation

Test is added to spec repo to validate other drivers handle IPv6 literals correctly. The tested scenario is:

• Connect with: mongodb://[::1]:27017/?replicaSet=rs
• Server responds as a secondary (putting the driver's topology state in ReplicaSetNoPrimary) and a "me":"[::1]:27017.
• Expect the server to be present. The bug from HELP-68823 triggered the server to be (unexpectedly) removed from the topology due to the mismatched me check.

Testing

Tested in mongodb/mongo-rust-driver#1327.

Fails on mongodb/mongo-rust-driver@206b99e (before fix)

$ cargo nextest run -- sdam::description::topology::test::sdam::rs
[...]
thread 'sdam::description::topology::test::sdam::rs' panicked at src/sdam/description/topology/test/sdam.rs:441:5:
assertion `left == right` failed: Secondary with IPv6 literal: 0
  left: 0
 right: 1

Passes on mongodb/mongo-rust-driver@1acffc4 (after fix).

---

Please complete the following before merging:

• [ ] Update changelog. (Tests only)
• Test changes in at least one language driver. (Tested in Rust)
• [ ] Test these changes against all server versions and topologies (including standalone, replica set, sharded
  clusters, and serverless). (N/A. Test mocks data to SDAM)
