Fix workflow: replace JS actions with shell commands

actions/checkout@v4 and actions/upload-artifact@v3 require Node.js
which is not in the debian:trixie container. Replace both with
pure shell equivalents:
- Checkout: git clone + git fetch/checkout via curl
- Artifacts: removed in favour of the Gitea release upload (curl)
