Resolve the problem the docker compose caused by the extensions tests (…

…#8024)

## Problem
The merging of #7818 caused the problem with the docker-compose file.
Running docker compose is now impossible due to the unavailability of
the neon-test-extensions:latest image

## Summary of changes
Fix the problem:
Add the latest tag to the neon-test-extensions image and use the
profiles feature of the docker-compose file to avoid loading the
neon-test-extensions container if it is not needed.
