Setup PKG Build Workflow for macOS

[vikman90]

Description

This issue focuses on creating a GitHub Actions workflow to automate the building of PKG packages for the Wazuh agent on macOS 14+. The workflow will target both Intel and Apple Silicon architectures.

Requirements

• Configure GitHub Actions to build PKG packages for macOS 14+.
• Set up the environment using tools like pkgbuild to create PKG installers.
• Target both Intel and Apple Silicon architectures.
• Ensure the PKG installer sets up the Wazuh agent as a launch daemon.
• Ensure the workflow generates .pkg files and stores them as artifacts for download.

Tasks

• Create a GitHub Actions workflow YAML file for the PKG build process.
• Install necessary tools for building PKG installers.
• Implement steps to build the Wazuh agent PKG installer for both target architectures.
• Store the generated .pkg files as artifacts in the proper Amazon S3 bucket.
• Configure the workflows to trigger automatically on GitHub events like pull requests or merges to the main branch.
• Include a manual trigger option for rebuilding the packages on-demand.
