[Feature]: Consider not using a source that requires authentication for "external" tests in CI

Description

Our "external" integration tests use Google Analytics and GitLab. This is fine to validate precisely authentication, but it also means that we have to manage secrets for these services in the repo settings.

Now, forks don't have access to these secrets, neither does dependabot (by default, can be copied verbatim to https://github.com/meltano/sdk/settings/secrets/dependabot) so we can't run the external tests pipeline on community-contributed PRs.

Ideally, we would an open source API application that we can start and seed data to as a docker container running in CI. We could safely pass hardcoded credentials to this local service.

A OSS product like listmonk.app or similar probably makes the most sense.
