feat: support unpacking binary from zip file

 This action only supports installing from releases where the release:
 
 - is tagged with the full `{major}.{minor}.{patch}` semantic version
-- contains raw binary assets (archives not supported)
+- contains raw binary assets or zip archives (zip archives must contain exactly one binary file)
 - assets are labeled with the binary name and [target triple] in the format `<binary name>-<target triple>`
+  - also supports assets labeled with underscore format: `<binary name>_<platform>_<arch>` (e.g., `fossa_linux_amd64`)
 
 You can create compatible releases with [semantic-release], using a workflow like [semantic-release-action/rust].
