Publish lib-jitsi-meet to npm as @jitsi/lib-jitsi-meet

After having some problems with building this library again and also having some community members they are publishing unofficial versions to npm (which can result in a security vulnerability for some users) I adress this topic again to have an official lib-jitsi-meet package.

I think this would be a low hanging fruit to do this automated in the CI/CD.
