[BUG]: macOS Stable Releases are named incorrectly

[TellowKrinkle]

Describe the Bug

When we create a stable release, we tag it with the stable release number. There's a chance the same commit is also tagged with an unstable release number. It appears our scripts end up including both numbers in the filename when creating an app bundle, separated by a newline.

(We currently use git tag --points-at HEAD to get the tag. I wonder if there's something supplied by GitHub Actions we could use instead, as from Git there's not really any way to know which tag is the "correct" one...)

Reproduction Steps

• Download the macOS release of PCSX2 stable v2.2.0 (doesn't need to be done on macOS)
• Untar it
• Look at the name of the .app bundle
• It's named PCSX2-v2.1.236\nv2.2.0.app

Edit: I manually replaced the release asset so you can't reproduce this anymore. It will happen again if we do the same process for the next stable PCSX2 release.

Expected Behavior

It should be named PCSX2-v2.2.0.app

PCSX2 Revision

v2.2.0

Operating System

macOS (or any with the ability to untar a .tar.xz, if you're just checking)
