Test GitHub Action Runners with Xcode 15.4 (#18)

# Test GitHub Action Runners with Xcode 15.4

## ♻️ Current situation & Problem
- We currently rely on our own runners as shown in #17 and had build
errors as also documented in
actions/runner-images#9511 (comment)

## ⚙️ Release Notes 
- Switch to GitHub-hosted runners and explore the situation after some
Xcode updates.
