Tilde (~) and Grave (`) Work Again

This fixes the regressions described in barrier issues #1531, #1407, and now #1836, where the barrier server can't send tilde or grave. It was caused by adding these keycodes to a list of modifiers for JIS keyboards, which is great if you're trying to type there, but the list applies to all keyboards, which breaks these keys for non-JIS keyboards.

Although I'm attaching a binary for an m1 Mac running Monterey (MacOS 12.4), I doubt my codesigning will work on your Mac. You should be able to re-sign it yourself by typing sudo codesign --force --deep --sign - /Applications/Barrier.app (adjust path to .app file if you don't put it in /Applications).

If anyone asks, I can create a binary for Catalina (MacOS 11), and/or x86 Macs, but the real solution is for the Barrier project to merge (@vladimirlagunov)[(https://github.com/vladimirlagunov]'s PR #1541 (or my newer PR #1711, that I created to pass the automated tests, and in the hope that the maintainers would notice it).
