Add build for arm64 arch

[bcmmbaga]

Fixes #4

[Copilot]

Pull Request Overview

This PR adds support for building packages for ARM64 architecture (aarch64) in addition to the existing x86_64 architecture. The changes restructure the GitHub Actions workflow to use a matrix build strategy and separate the build and release jobs.

• Introduces matrix build strategy to build for both x86_64 and aarch64 architectures
• Adds architecture-specific naming for build artifacts
• Separates the release creation into a dedicated job that depends on the build job
