Expand files uploaded in GitHub Release workflow

Updated the `files` parameter in the `Upload installers to GitHub Release` step of `release.yml` to include additional assets.

Previously, only `Output/Publish/Math.Editor*` files were uploaded. Now, the workflow also includes `Output/Publish/releases.*.json` files.

This change ensures that release-related metadata or assets are included in the GitHub Release. The multi-line format improves readability and simplifies future updates.
