adapters/kafkastreamer: bump testcontainers-go to v0.43.0

[andrewwormald]

Summary

• Bumps testcontainers-go (and the modules/kafka submodule) from v0.35.0 to v0.43.0 in adapters/kafkastreamer.
• Clears most of the remaining Dependabot alerts rooted in this module's outdated transitive deps: docker/docker and containerd/containerd are replaced by the lighter moby/moby/api + moby/moby/client split, the google.golang.org/grpc dependency is dropped entirely, and go.opentelemetry.io/otel moves to v1.44.0.
• testcontainers-go is test-only here (spins up a Kafka broker for integration tests) — no change to the adapter's shipped runtime code. go build / go vet are clean.

⚠️ Known issue — needs verification in CI before merge

Locally (Docker via Rancher Desktop), the kafkastreamer integration tests fail after this bump: kafkaInstance.Brokers(ctx) — the testcontainers Kafka module's own documented accessor — returns the container's internal Docker hostname (its container ID) instead of a host-reachable address, so every client connection fails with dial tcp: lookup <container-id>: no such host.

This looks like a testcontainers-go Kafka-module regression in advertised-listener resolution under non-Docker-Desktop container runtimes (see testcontainers/testcontainers-go#2748 for the same class of bug in an earlier version). It may not reproduce under GitHub Actions' standard Docker-in-Docker setup — please confirm the Integration Tests (Testcontainers) CI check passes before merging this one. If it fails in CI too, this bump needs to stay open pending a fix (pin to a testcontainers-go patch version that resolves the listener issue, or adjust how the adapter/tests obtain the broker address).

Test plan

• go build ./...
• go vet ./...
• go test -v -timeout=10m ./... — fails locally (see above); pending CI confirmation

📝 Walkthrough

Walkthrough

Updated the Kafka streamer Go module’s direct testify and Testcontainers dependencies. Refreshed numerous indirect dependencies across container tooling, compression, Prometheus, OpenTelemetry, and golang.org/x modules, while removing superseded entries and adding newer transitive modules.

Poem

I’m a rabbit with modules to thump,
Fresh versions now hop with a jump.
Test containers align,
Telemetry can shine,
While old dependency carrots go plump.
