[CICD] Release docker images on GHCR

🚀 Feature Description and Motivation

Since Docker Hub has pull limits, switching to using GitHub Container Registry might be better for releasing our images. It could save us some hassle and keep things running smoothly.

Agree. it used to have GHCR build

aibrix/.github/workflows/docker-push-images.yml

Lines 39 to 46 in fcc0896

	# TODO: Disable GHCR at this moment after org transfer, let's enable it later.
	# - name: Build Container Images with Github Container Registry prefix
	# run: |
	# GIT_COMMIT_HASH=${{ github.sha }} AIBRIX_CONTAINER_REGISTRY_NAMESPACE=ghcr.io/aibrix make docker-build-all
	#
	# - name: Push Container Images to Github Container Registry
	# run: |
	# GIT_COMMIT_HASH=${{ github.sha }} AIBRIX_CONTAINER_REGISTRY_NAMESPACE=ghcr.io/aibrix make docker-push-all

After we transferred the repo, it doesn't have package write permission. We can resolve this issue either adopting previous orgs or ask vLLM maintainers to grant the permission here.
