macOS: fixes the "damaged" error

Downloaded builds now open correctly on Apple Silicon. Earlier releases had a
broken signature seal that macOS reported as "damaged". The app bundle is now
re-sealed at build time, so it opens via right click then Open.

If you already downloaded an earlier build, you can clear the quarantine flag:

xattr -dr com.apple.quarantine /Applications/Peek.app

Thanks to @brandonjones24 for reporting this and the initial fix.
