Version release script

Summary:npm-publish.js is not cohesive enough: besides building and publishing it also modifies some files.

It is better to have a separate script that will bump versions, make a commit and tag it.

scripts/bump-oss-version.js does exactly that.

This simplifies release process and allows manual release to npm if CI is not available.
