Automatic fallback to docker-compose v2

[cristianrgreco]

Resolves #617

Testcontainers uses the docker-compose library for interacting with docker-compose. This library invokes the underlying docker-compose CLI, with commands such as docker-compose up. This works fine when the docker-compose binary is installed. Docker-compose is now being included in the main docker binary, and accessible via docker compose. When this is the case, the docker-compose functionality fails because the library cannot find the docker-compose binary. Support for docker compose was added recently, but needs to be used explicitly.

This PR tries to find a docker-compose binary, first with the old method, and then with the new (to avoid a breaking change), and will use a suitable client depending on which binary is found.

Tested locally by moving my docker-compose binary out of the PATH and seeing the fallback work.
