fix: gradle deprecation warnings about property assignment (#1821)

When building a plain Android Cordova app without plugins, there will be Gradle depraction warnings: `Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.`. Compiling it with `--warning-mode all` shows, that some properties are assigned without an `=`, which will not be supported any longer with Gradle 10.0.
