When you run `npm version`, it also tries to make a git commit and a git
tag. However, we are not doing anything with this and CI doesn't know
who the committer is.
This fails because we usually use node 14 or 16, which has a
package-lock.json version of `2`. However on node 12, this version is
`1`. This means that after an npm install the package-lock.json is
touched and thus `npm version` fails because git is in a dirty
directory.
Adding a `--force` is not ideal, but also not really an issue since the
only thing that could change is the package-lock.json and this is not
published to npm anyways.
* ensure we build before the tests
Our tests require that for now. Will probably improve this in the
future.
* improve insiders version name
This will make it consistent with previously published versions.
