in examples/hotrod we have two docker compose files, the default one starts jaeger v1 and the one that starts jaeger v2 has non-standard name docker-compose-v2.yml.

We want to swap that so that the default file is for v2 and the v1 file is called docker-compose-v1.yml.

The core of the issue is not just renaming the file, but updating references to that that might exist, like the CI scripts or the READMEs.

For good measure we should do the same with docker-compose/monitor/docker-compose-v2.yml
