docker_compose_v2: Pull always check behavior to ignore pulls

[saibotk]

SUMMARY

I am using pull: always to ensure that docker images that have been rebuilt on the same tag are also always pulled.
But with the pull option set to always, the module will always report a change. I think we might be able to detect if it has actually pulled something or not via the output.

Ideally the step should only be marked as changed, when the containers were recreated.
I saw that you, @felixfontein, already did something similar in #797, can we maybe introduce that to the docker_compose_v2 module too?

Thanks!
And huge thanks for migrating to compose v2! I could finally remove all the ugly workarounds for the python library installation <3 you're amazing.

The kind of checks used for docker_container won't work here since the output is usually not sufficient. But considering Pulling only when a container is (re-)created is a good idea, that should work.

#803 fixes this.
