Zig versions support.

Hi there, it is hard to work with one version of a language when you are contributing to different open source applications. You might need different versions of a language for different projects.

I have created a pull request addressing the solution to above issue.
Please consider it and review the pr.

Thank you

Hi! To be honest, I don't get your use case, could you provide more context? Do you want to use a single Dev Container for working on multiple different apps (repositories)?
