bump the version

I miss some context. What is the issue we are trying to solve here?

So, up until now we would run Zwik on Rosetta so that compatibility is guaranteed with x86 installers and packages, right? With this change, if the installer is ARM64 and packages are x86, will it still work?

I think we will need to start supporting arm64 packages as well, but that is out of scope of this PR, and of this repo. This is simply to allow macOS users to use zwik. The packages then it's going to be a different story.

But aren't macOS users already able to use Zwik trough Rosetta? And about the second question: If the installer is ARM64 and packages are x86, will it still work?
