[Imprv] Bumpup ansible core versions to avoid EOL versions

[bhati-pradeep]

Describe the request
In runtime.yml, >=2.11.6 ansible core dependency was used. It has gone EOL and all other versions till 2.14.0 also went EOL. Ref: https://docs.ansible.com/ansible/latest/reference_appendices/release_and_maintenance.html

Bump up the ansible core requirements to >=2.14.0. Ref: https://docs.ansible.com/ansible/latest/reference_appendices/release_and_maintenance.html#:~:text=PowerShell%203%20%2D%205.1-,2.14,-GA%3A%2007%20Nov

1. Drop support for python < 3.9 as ansible core 2.14.0 supports python >=3.9
2. Also this change comes up with lint errors which needs to be fixed as well.
3. Remove pipeline jobs using python < 3.9
