ci(play): fix gradlew exec bit and align store password secret name (#42)

Two fixes for the failing 'Publish to Google Play' run (#41 follow-up):

1. gradlew was committed with mode 100644, so the runner refused to
   execute it ('./gradlew: Permission denied', exit 126). Set the
   execute bit in the index via 'git update-index --chmod=+x gradlew'
   so checkouts on Linux runners can invoke it directly.

2. The workflow read the store password from a secret named
   ANDROID_KEYSTORE_PASSWORD, but the matching Gradle property in
   app/build.gradle is ANDROID_STORE_PASSWORD. Renamed the workflow
   reference + README documentation to ANDROID_STORE_PASSWORD so all
   five secrets line up 1:1 with the Gradle property names.
