Rename package to scoped @valknar/vpinball-wasm

Reverts the earlier unscoping: an unscoped package on a Gitea npm
registry has no `.npmrc` mapping a consumer can use other than pinning
the exact tarball URL, since Gitea's registry doesn't proxy npmjs.org
and only scoped packages support the standard `@scope:registry=`
config. Scoping restores that: consumers add one `@valknar:registry=`
line and depend on a normal semver range.
