fix(ci): repair corrupted rsr-antipattern.yml on this branch

Repairs the corrupted `rsr-antipattern.yml` from the prior commit on this branch. See hyperpolymath/stapeln#34 for the full root-cause writeup — the original sweep built its canonical via `gh api --jq '.content'` piped through PowerShell, but `gh` line-wraps base64 in the terminal pipe, so each chunk was decoded separately and the rejoined file has mid-word line breaks (`# SPDX-License-Id\nentifier:`, `name: RSR A\nnti-Pattern`, etc.). GitHub Actions can't parse the resulting YAML — the workflow completes in 0 seconds with no jobs.

This commit overwrites the file with the correct content, built via raw byte download (`Accept: application/vnd.github.raw`) and `[System.IO.File]::WriteAllBytes` so no pipe ever touches the bytes. Round-trip byte-verified against canonical.
