v8.8.1

• "Convert…" opens Workshop with the game picked again. Since 8.7.0, Convert… from Files,
  a game page, a Collection card and the Send as One Image card opened an empty Workshop:
  they still linked to the old Convert screen, and the redirect to Workshop lost the game.
  They go straight to Workshop now, and a test keeps every link off the old screens.
• The web UI and Docker take .zip, .7z and .rar archives (#529). Pick an archive on the
  server and it is unpacked on the way to the PS5, as in the desktop app: nothing extra is
  written next to it on the NAS. The web UI used to refuse archives with "isn't available in
  the browser yet".
