Prepare release 1.56.0

[yurishkuro]

• coincidentally GitHub runners removed docker-compose (v1) command on Apr-1, so I added a commit that changes everything to use docker compose (v2)
• the all-in-one integration tests were failing because jaeger logo file in ui static assets got a different hash for some reason. I changed the test to read the actual file name from index.html and then try to load it.
