Change the way Gradle find code signing configuration

[jfoucry]

Hello,

For now, If we want to create a new release, we need to Generate a signed Bundle / APK... give the path to the keystore, the keystore password, the keyAlias and the KeyPassword.

In gradle we can use variable and secret file (which will not be committed) id order to simplify this generation.

see Pilldroid build.gradle file.
or the documentation

This change has an impact in Workflow Github to build app ?
