v0.4.0

Changes:

• Delete legacy deploy directory. This was used in the previous versions to allow Kustomize to deploy Replika using remote manifests. Now, we are publishing manifests bundles directly in the releases. This will make the manifests atomic.
• Implement bundle-build on Makefile
• Add deprecation notice for directory deploy and update README reflecting all deployment possibilities
• Automate artifacts (bundles, binaries, Docker images) building in releases flow
• Docker images are now published in Github Container Registry
