ci: Optimize APK output naming

[Chumor]

Overview

Refactor APK output naming to clearly distinguish between Release and CI / Staging builds.

Changes

• Version (v) is derived from the latest Git tag.
• Release builds: LogFox-v<versionName>-release.apk
• CI / Staging builds: LogFox-v<versionName>-<short_commit>-release.apk

Verification

I have tested this repeatedly in my repository. The generated APKs can be downloaded from this Actions run:

Because previously only the short commit hash was used, making it hard to tell which version is newer.

Currently there's an unnecessary v perfix appended before the numbers in the versionName in the APK's AndroidManifest, I hope this PR removes it, because the App Info shows version v, which isn't ok.

@drogga why does it even bother u ahaha

...because it was just wrong, but I can see you've made changes since, so thx, but to clarify - I have absolutely no issues with and don't mind (in fact no one should) if the "v" prefix is in the file names of releases and CI artifacts, it's even preferable, but it seems like both are tied for now and can't exclude only the versionName, unless this PR tackles exactly this (IDK).
