Fix Forgejo workflows for the actual server capabilities

- package.yml: use correct Arch registry upload (octet-stream + binary body
  + PUT /api/packages/Breadway/arch/os), drop --privileged, remove
  actions/checkout (archlinux image has no Node) in favour of a manual
  shell clone, use the built-in Actions token instead of a stored secret,
  and --nocheck (tests belong in CI, not packaging)
- mirror.yml: clone --mirror + explicit refs/heads + refs/tags push with
  --prune, instead of pushing refs/remotes pollution from a checkout
- pacman.conf: correct Server URL to the Forgejo Arch registry format

Requires only the GITHUB_MIRROR_TOKEN secret (GitHub PAT, repo scope) for
the mirror job; package publishing uses the automatic per-run token.
