Proposal: Mirror repository on SourceHut and/or Codeberg for accessibility and vendor independence

I'd like to propose mirroring the iSH repository on SourceHut and/or Codeberg in addition to GitHub. This would provide benefits for accessibility, reduce vendor lock-in, and better serve users who prefer to avoid proprietary JavaScript.

Currently, iSH is only hosted on GitHub. While GitHub is convenient, this creates several friction points:

• JavaScript concerns: GitHub's web interface relies heavily on proprietary JavaScript, which can be problematic for users who prefer lightweight browsing, prefer to avoid proprietary software, or use JS-blocking tools.

• Vendor lock-in: Hosting only on a single proprietary platform makes the project dependent on GitHub's continued availability and policies.

• User choice: Some users prefer forges that align with open-source principles (like SourceHut or Codeberg), and mirrors would make the project more accessible to them without requiring GitHub accounts.

  I propose maintaining mirrors on either: - SourceHut (preferred, due to minimal JS and accessibility-first design) - Codeberg (Forgejo-based, community-driven alternative)

  These could be read-only mirrors synced from the primary GitHub repo, or if preferred, full mirrors where contributions are accepted via pull requests on either platform. A simple automated sync (like a cron job or webhook) could keep them current with minimal overhead. I understand you are unpaid open source maintainers working out of your free time so I respect your opinion if you find it too inconvenient. I'd also be happy to help set up and maintain the mirrors if that would ease the burden.
