Deprecated: Using ${var} in strings is deprecated, use {$var} instead

Problem/Motivation

We see a lot of deprecated code in opigno modules like opigno_statistics, opigno_learning_path, opigno_moxtra to name a few but a lot of opigno module throwing deprecated code and function alert in logs for Drupal version 10.3.6. Attached is the screenshot for the reference.

Steps to reproduce

Upgrade opigno_lms to 3.2.7 and Drupal to 10.3.6 , check in the watchdog logs
