What did you do?

I pushed a new package/module to github.com/aclements/go-misc/stress2.

What did you expect to see?

I expected pkg.go.dev to try fetching the module since it wasn't in its cache, or at least to provide an easy way to pull the latest version (a link or button).

What did you see instead?

A 404 page. It includes a link to instructions on how to add a package, but those instructions aren't easy to follow. The package I pushed is a "main" package, so it's not going to be imported by something else that would pull it into the cache. And since I haven't version tagged it, I have no idea how to form the appropriate proxy.golang.org request. Finally, if this was an existing package I had updated and I simply wanted to refresh the documentation, pkg.go.dev wouldn't even offer me the link to the instructions.

Fishing around some more, this appears to be related to #37106, #37002, and #36811. Feel free to close as a dup if you feel this bug doesn't add anything. Thanks!
