chore: Add fvm_version input and update environment variables (#4651)

* chore: Add fvm_version input and update environment variables

* Add VERSION input to action.yaml environment variables

* Add Docker API version environment variable

Set Docker API version for local-k8 run mode.

* Add DOCKER_API_VERSION environment variable for K3d

* Use global environment variable for that one

Removed DOCKER_API_VERSION environment variable from multiple jobs in CI workflow.

* Add DOCKER_API_VERSION to merge_queue workflow

* Fix docker_push job for Docker API 1.44 compatibility

- Add Docker Buildx setup step before login
- Replace docker manifest commands with docker buildx imagetools create
- Maintain existing image naming convention with -amd64 and -arm64v8 suffixes
- Keep DOCKER_API_VERSION at 1.44 (no downgrade)

This resolves the "is a manifest list" error that occurs with Docker API 1.44's stricter handling of manifest lists vs. single-platform images.
