Bumps version to 3.0.2

@cgravill I suggest we drop any use of "beta" and "alpha" and just regularly bump the major/minor version numbers forward from now on

[cgravill]

Sounds good. The last major release (3.0.1) had already dropped beta and alpha - previous versions really were unstable in places.

It would be good to avoid duplicating the release notes with https://github.com/fsprojects/IfSharp/releases I've not done it before it but it must be possible to create releases via API.

Yes, let's add code to automate the release process including git tag (hence docker tag) and push to git

Will do that in a separate PR
