fix(e2e-android): read detox gradle version from node_modules, not a literal

The hardcoded 20.50.1 survived the detox bump; the local Detox-android
maven dir only ships the installed version's artifacts, so gradle fell
through to remote repos and choked on a 404 page as a POM. Resolving
the version from node_modules/detox/package.json makes future bumps a
one-place change. Verified: :app:dependencies resolves com.wix:detox:20.51.4.
