Our git repo package does not appear in package list when added

[FairlySadPanda]

Summary
When adding our Github-stored package, VRCBilliards/vrcbce, to the list of Github repos, our package does not appear in the list.

Steps to reproduce

1. Create a new VCC repo
2. Add "VRCBilliards/vrcbce" to the githubRepos array in the repo's source.json file.
3. Commit the change and wait for the Github Action to complete.
4. Visit the published website.

Expected outcome
The added package should appear in the list.

Actual outcome
The added package does not appear in the list, and no error or explanation is reported via tooling or the website.

As far as is known our repo should work with the package listing website tool. When cloned, the package can be added manually to CreatorCompanion.

The package is stored at this repo: https://github.com/VRCBilliards/vrcbce

My expectation is that we've configured this incorrectly but it's not obvious where.

From what i see, the reason why is that the Github Release associated with the Github repo doesn't follow the vpm format. When you go on https://github.com/VRCBilliards/vrcbce the release only have a unitypackage. It should have a zip, a package.json, and similar items.

If you look for example https://github.com/BlackStartx/VRC-Gesture-Manager, you will have a unity package and a zip containing the package.json having the data required by the list builder.

This is ran by the package-list-action task here https://github.com/vrchat-community/package-list-action/blob/main/PackageBuilder/Build.cs
