Add support for installing openfeature CLI via Homebrew

Feature Request: Add openfeature to Homebrew

Goal:
Add support for installing the openfeature CLI via Homebrew, making it easier for users on macOS (and Linux via Linuxbrew) to install and update the tool.

Tasks:

• Create and submit a Homebrew formula for the openfeature CLI.
• Document installation steps in the project README.
• Optionally, automate publishing updates to Homebrew when new releases are made.

Notes:

• Reference similar tools' formula submissions for guidance.
• Ensure compliance with Homebrew's formula requirements and best practices.
• Consider collaborating with the Homebrew maintainers if needed.

Benefit:
Simplifies installation and distribution for the community, increases accessibility for users native to the Homebrew ecosystem.

This is a great idea. I also suggest ensuring that shell completion scripts are installed along with the Homebrew formula.
