feat: support unzip with fetch

We use busybox which uses libarchive by default. Doesn't libarchive already support extracting zip files?

I got this error

Looking forward to this PR to bring Gradle package in the Wofli, which is a .zip file.

the issue from what I've figured out is busybox doesn't support automatic resolution of archive types unlike gnu tar so we'd need a if check for every type of archive we intend to support :/
