The most recent documentation monthly meeting discussed providing a dashboard for the translations and progress.

Suggestions:

• [x] Link to Maciej's dashoard from the devguide
  • https://m-aciek.github.io/pydocs-translation-dashboard/
  • https://github.com/m-aciek/pydocs-translation-dashboard/
  • cc @m-aciek
• [x] Add translation contribution links to the dashboard
• [x] ~~Perhaps move the dashboard to docs.python.org/translations~~ Currently hosted https://python-docs-translations.github.io/dashboard/ which is good for now
  • ~~This could be achieved by plugging in to docsbuild-scripts~~

Relevant prior art: https://translations.react.dev/
