Update release workflow (#102)

This PR merges the `release.yml` workflow with `version.yml` as
`version-and-release.yml`.

How it works:
- now the workflow is split into 2 jobs: `version` and `publish`
- `version` is responsible for
- creating/update release PR if needed when the change is not a new
version (has uncommitted changelog)
- version packages and create tags and GitHub releases when this is a
new version (committed changelog)
- after publishing by `changesets` action, the output contains versions
of the released packages
- this output is transformed by `jq` in a format to easily consume in
the next job
- `publish` does what `release.yml` used to do:
  - builds, tests, packs
  - uploads artifacts to the GitHub releases
  - now it uses tags for each package as these releases are now separate
