Update npm package automatically after increasing version in package.json

[Kouprin]

Currently we need to do it manually.
The steps are:

• create a new npm user (or use boatnear if it can be used for this purpose)
• add a hook that starts deployment process automatically right after changing the version
• add the same for -sol and -rs repos
