Add workflow for publishing rust binaries and Docker images

[mnsanfilippo]

This update introduces several key enhancements and configurations:

1. GitHub Actions for CI/CD:

   • Fixed the workflow in .github/workflows/release.yaml to automate the publishing of Rust binaries and Docker images. This workflow triggers on-release events.

   • Introduced custom GitHub Actions in .github/actions/publish-binaries/action.yaml and .github/actions/publish-docker-image/action.yaml to handle the publishing of Rust binaries and Docker images, respectively.

2. Dockerfile:

   • Added a Dockerfile to build Docker images for the pathfinder application.

3. Dependency Updates:

   • Updated Cargo.toml to switch rdkafka to use cmake-build and added openssl and openssl-sys with vendored (required to build for aarch64)

4. CODEOWNERS:

   • Added a .github/CODEOWNERS file to specify that @jucr-io is the code owner for the repository, ensuring that they are automatically requested for reviews on pull requests.
