fix(android): Move noisy debug logging out of "quiet" log level. (#844)

Each time building our app, this library causes a message like this
one to be printed, sometimes twice:

  > Configure project :react-native-webview
  :react-native-webview:reactNativeAndroidRoot /home/greg/z/mobile/node_modules/react-native/android

Worse, the message comes through even if I silence all normal
progress messages and warnings, with `./gradlew --quiet`.

It turns out that the `logger.quiet` method which these log lines are
using has a confusing name.  It doesn't mean "log quietly", but more
like the opposite: "log even when asked to keep things quiet".  See
documentation on Gradle log levels:
  https://docs.gradle.org/current/userguide/logging.html

So, remove the noise by switching to `logger.info`.  This avoids
bothering the user by default, and keeps the information readily
available if desired by passing `--info` to Gradle.
