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.

android/build.gradle

       name androidSourcesName
     }
 
-    logger.quiet(":${project.name}:reactNativeAndroidRoot ${defaultDir.canonicalPath}")
+    logger.info(":${project.name}:reactNativeAndroidRoot ${defaultDir.canonicalPath}")
     found = true
   } else {
     def parentDir = rootProject.projectDir
           name androidSourcesName
         }
 
-        logger.quiet(":${project.name}:reactNativeAndroidRoot ${androidPrebuiltBinaryDir.canonicalPath}")
+        logger.info(":${project.name}:reactNativeAndroidRoot ${androidPrebuiltBinaryDir.canonicalPath}")
         found = true
       } else if (androidSourcesDir.exists()) {
         maven {
           name androidSourcesName
         }
 
-        logger.quiet(":${project.name}:reactNativeAndroidRoot ${androidSourcesDir.canonicalPath}")
+        logger.info(":${project.name}:reactNativeAndroidRoot ${androidSourcesDir.canonicalPath}")
         found = true
       }
     })
