Description

This PR expands the "Rate Us" functionality on the About Page by dynamically detecting the installation source (added PackageManager.getInstallSourceInfo method for Android 11+ along with existing getInstallerPackageName()) and rendering a contextual subtitle and intent link (Google Play, F-Droid, Amazon, and Galaxy Store).
Previously, the rating item only showed a generic "Rate Scribe" and lacked support for alternative app stores like Amazon and Samsung. Now, it accurately reflects where the user downloaded the app and routes them there directly.

The external store URLs are constructed dynamically using the app's package name (e.g., https://f-droid.org/packages/${context.packageName}, https://www.amazon.com/gp/mas/dl/android?p=${context.packageName}) as dummy links, which can be modified later as required.

For other third party stores, we default to Google Play Store, which again, can be modified as required.

Hey @ashb155
Thanks for the PR.

https://github.com/ashb155/Scribe-Android/blob/f132f103d571cc0780d4b339c43976e2a92eb1c8/app/src/main/java/be/scri/helpers/ui/RatingHelper.kt#L83-L95

Instead of the inbuild review flow fail leading to a toast could the user be instead be redirected to the playstore page. This would be better for the user experience.
