Subject: fix: enable partition alloc ref count size for MacOS 13+

Modifies an existing check to check for all versions of MacOS 13
or higher, including MacOS 14 and potential beta versions.

This patch is currently being added upstream, and can be removed
when we integrate the upstream changes into Electron.
