Downloading the full app through the stub fails

[binarynoise]

There is a problem when you hide the Manager and want to use it from a secondary user. Only the stub gets installed for him and the stub prompts the user to download the full app, so it can load it and show the Manager. That fails.
In logcat we find java.io.FileNotFoundException: https://cdn.jsdelivr.net/gh/topjohnwu/magisk-files@v25.200/app-release.apk

In https://github.com/programminghoch10/Lygisk/blob/master/stub/build.gradle.kts#L17 there is a link to some Magisk APK, getting the correct version by looking at https://github.com/programminghoch10/Lygisk/blob/master/config.prop.sample#L7 which we don't override, so the lookup fails as the file does not exist because the correct version would be v25.2 instead of v25.200.

Fixing the version code and querying https://cdn.jsdelivr.net/gh/topjohnwu/magisk-files@${Config.version}/app-release.apk would yield nothing, as the original Magisk app would be downloaded, which has the wrong signature and doesn't have our addond install fixes.
We might be able to replace the url to match it to our deploy framework:
https://raw.githubusercontent.com/programminghoch10/Lygisk/deploy/stable/app-release.apk
Though I'd rather kill stub completely. Everywhere it is used we might as well place the complete manager, why is stub even needed anymore?
