[DOCS] Add flake8 linter to Github Actions workflows

[merobi-hub]

Signed-off-by: Michael Robinson [email protected]

Problem

A linter could be configured to check new Python source files for copyright and license headers.

Solution

This PR adds flake8 to Super_Linter in Github Actions and configures it with a plugin for checking files for copyright text.
