Migrate flake8 ignore to use Athena ones
At the moment we use
https://gitlab.cern.ch/easyjet/easyjet/-/blob/main/.gitlab/pipelines/.linting-gitlab-ci.yaml#L12
--ignore=E231,E241,W503,E741
while flake8 in Athena is configured with --ignore=E701,E702,E704,E741
.
We should harmonise with Athena and fix the potentially breaking occurences we already have in for this.
