♻️ Maintenance/fix docker buildx in CI

[sanderegg]

What do these changes do?

Docker buildx v0.6.0 seems to have broken the docker bake application. the baked cookies are not getting the environment variables expanded as they used to in the version before.
Until this is clarified see issue the version of docker buildx will be set to 0.5.1.
Coming from the PR #2360, the github action to setup docker buildx with a specific version will be used.

bonus:

• dependabot on github actions added
• use github matrix to set versions on docker-compose and docker buildx
