Subject: [PATCH] chore: add automatic github release (#4466)

This will automatically do a github release with the correct changelog entry and the built zip file.
If a publish is made with `--tag next` it will mark the release as a pre-release.

To use, just add `VJS_GITHUB_USER` and `VJS_GITHUB_TOKEN` env variables as part of the publish command:
```sh
$ VJS_GITHUB_USER=gkatsev VJS_GITHUB_TOKEN=test_token npm publish --tag next
```
