github/workflow: pylint checker update

pylint github workflow is currently broken due to following
error:

GitHub Actions / .github/workflows/pylint.yml
Invalid workflow file
You have an error in your yaml syntax on line 6

A mix of spaces and tab usage is causing this error. Fix
the formatting error.

Also update the python verion list to include 3.13 and
3.14. These versions are available with newer distributions.
