added always on display action and uprgraded gradle version

[TheNoumanDev]

Ticket: https://pub.dev/packages/wakelock_plus

Example EDL of action:

wakelock:
  enable: true # could be true and false
  onComplete: |
    console.log('Wakelock enabled - screen will stay awake');
  onError: |
    console.log('Failed to enable wakelock');

And we can get the current status from using ensemble.device.wakelockEnabled

Its latest version required package_info_plus to be upgraded, and package_info_plus required the latest Kotlin and gradle version.

enable should not be required, it should be true by default

PS: remove unnecessary print statements
