Zip slices to preserve symlinks (#46387)

Summary:
When creating Hermes in CI, we build it for MacOS and Mac Catalyst as well.
The slices for these platforms requires symlinks to work properly.
The upload artifacts action on github, when applied to folders, follows the symlinks and copies the destination folder. The result is that Hermes for macOS and Catalyst does not work as expected.

This should fix https://github.com/facebook/react-native/issues/46213.
