The texlive bundle wasn't updated since 2018?

So here I am, running tectonic 1.1.15 on a new computer for the first time, and I see this:

note: connecting to https://archive.org/services/purl/net/pkgwpub/tectonic-default
note: resolved to https://tectonic.newton.cx/bundles/tlextras-2018.1r0/bundle.tar
note: downloading index https://tectonic.newton.cx/bundles/tlextras-2018.1r0/bundle.tar.index.gz

I also noticed https://github.com/tectonic-typesetting/tectonic-staging hasn’t had commits since 2018. Is it supposed to be updated periodically? Manually or by a CI?

Updated when @pkgw feels like it… I don’t know if he’s up for automating that

Would @pkgw be willing to accept a PR that will setup GitHub actions to automate that?
