CI: automatically publish to npmjs @next tag on push to master

[vojtechsimetka]

This has been discussed on our roundtable on March 31st. Here is a dump of the proposal:

• rationale
  • we are anyways claiming that master always works
  • this truly gives the right weight to the bee-js@next idea and ppl (including us) being able to test it
• proposal
  • add ci action that does a pre-release to npmjs automatically on each merge to master
  • remove the manual pre-release mechanism

Sounds good to me 👍

I am just wondering if it does not make sense still to keep the pre-release mechanism? Maybe for "release candidates" testing?

Yes but then probably it should be extended to have a functionality to provide specific commit to build from.
