Create new major version for Drupal 9

Problem/Motivation

As of new Simfony 4.3 version, we can't make module compatible both 8.x and 9.x cores we need to create a new module version.

Steps to reproduce

Install 8.x-3.1 version on Drupal 9 core, enable the module and open any page on the site. There will be warnings about FilterResponseEvent class that deprecated.

Proposed resolution

Create a new major module version to support Drupal 9 core.

Remaining tasks

Update module to be compatible with Simfony 4.3 version. Both 8.x and 9.x should have the same functionality after fixes applied to a code.
