Update Password Policy from 8.x-3.0-beta1 to 8.x-3.0 ( ~3.0 ) and remove applied patches

Problem/Motivation

Password Policy 8.x-3.0 Stable release which covered by the Drupal Security Team was released 30 June 2021
https://www.drupal.org/project/password_policy/releases/8.x-3.0

The following used patches were committed into the version

• #2971079: Can't edit user profile because password policy validates even when password unchanged
• #3154140: Only force password change if new policies are applicable

Proposed resolution

• Update the Password Policy module to stable 3.0
