Create a publisher to Cloudflare R2 Bucket #4124

Pre-flight checklist

• I have read the contribution documentation for this project.
• I agree to follow the code of conduct that this project uses.
• I have searched the issue tracker for a feature request that matches the one I want to file, without success.

Problem description

I am implementing auto updates in an Electron application with Forge, and I noticed that there is no implementation for Cloudflare R2. It has features very similar to AWS S3 Bucket, and I think it would be a great addition to the project.

Proposed solution

Creation of a package called publisher-r2 with the respective integration

Alternatives considered

Use the S3 or other publisher
