Is your feature request related to a problem? Please describe.
Yes, minimallib build (rdkit-js) is not in azure pipelines for each rdkit PRs. This can cause us to realize this is broken after the fact, and not proactively. This also can cause delays in releasing the npm package anytime there is a new rdkit release.

Describe the solution you'd like
Adding an azure pipeline file for minimal lib

Describe alternatives you've considered
GitHub action in rdkit-js, which doesn't solve the problem really, and is more complicated than anything.
