CI: update CDN publish after migration (#6100)

https://github.com/transloadit/api2/blob/main/docs/releases-bucket.md

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Switch CDN publishing from Edgly to S3-compatible Cloudflare R2/Bunny
with new env vars and updated upload script/workflows.
> 
> - **CI/CD Workflows**
> - Replace `EDGLY_*` creds with
`AWS_ACCESS_KEY_ID`/`AWS_SECRET_ACCESS_KEY` and set `AWS_REGION`,
`S3_BUCKET`, `S3_ENDPOINT` in `manual-cdn.yml` and `release.yml`.
> - Use updated env when running `upload-to-cdn.js` for both normal and
`--force` uploads.
> - **Upload Script (`packages/uppy/upload-to-cdn.js`)**
> - Switch to S3-compatible client targeting Cloudflare R2 (`endpoint`,
`forcePathStyle`) and read bucket/region from env.
> - Validate required env vars (`AWS_ACCESS_KEY_ID`,
`AWS_SECRET_ACCESS_KEY`, `S3_ENDPOINT`, `S3_BUCKET`).
> - Derive version from local `package.json` when uploading local
builds; keep npm tarball path for remote versions.
>   - Update comments/paths; remove all `EDGLY_*` references.
