Add back in .zip as a release artifact download option

[buidav]

💡 Summary

PR #499 removes the .zip. However, the documentation still mentions we offer .zip as a release artifact option and zip is more user friendly compared to .tar.gz for specific userbases

Motivation and context

Keep previous release artifact behavior.

Implementation notes

Requires updates to the new release workflow.

Acceptance criteria

Zip is readded as an artifact.

I think GitHub provides the ZIP as a "freebie". This is the result of a "mock" release of ScubaGoggles:

I'm currently generating the .tar.gz, but it looks like that one's free, too.

@buidav any thoughts?

That's the entire source repository if we want to remove extraneous files such as tests and workflows we'll need to create an custom zip artifact.
Note. This is also to align ScubaGoggles with ScubaGear's release assets https://github.com/cisagov/ScubaGear/releases/tag/v1.4.0 where a separate zip asset is created with integration tests removed and code signed (though Goggles doesn't need code signing).

Also another note we can't keep track of downloads if someone downloads a not release artifact zip like that source code zip.
