Add version tag to bundled artifacts

[ChrisNeedham24]

Currently the bundled zips don't have the version of microcosm in their name. This would be useful to have.

This action should be a good start.

This would also mean a process change would need to occur where the head commit of pull requests are tagged before merge, if they are to result in a version increment.

Turns out you can name artifacts in releases - that's good enough for this.
