updating macOS binaries, fixing darwin-arm64 non-static build issue

[marcelblum]

The currently provided darwin-arm64 build is not 100% static. On my M1 Mac when I try to run it I get missing Homebrew dependency errors similar to those mentioned in https://github.com/SavageCore/node-ffprobe-installer/pull/200

This PR includes updated macOS builds for both arches. The darwin-arm64 build is from a different source (new to this repo I think), https://www.osxexperts.net/ which has been providing quality ffmpeg arm builds for several years now, and I can confirm it is a full static build (>50mb). I figured I'd also update the Intel Mac build while I was at it so I've included the latest darwin-x64 build from evermeet.cx, same source as before officially sanctioned by the FFmpeg org.

This bumps both ffprobe versions to 8.0. I don't know if you prefer to have the versions for all platforms in sync before publishing a release, but I am working on my Mac today so I've only updated those builds...
