CI: add a workflow to show flake8/mypy violations in modified files of a PR (#1513)

* CI: add a workflow to show flake8 violations in modified files of a PR * modify a file to trigger the lint check * CI: add a workflow to show mypy violations in modified files of a PR * modify a file to trigger the type check * Split flake8 and mypy into two parallel jobs; run a variant of the workflow on push event; modify a file to trigger the push workflow * fail the task if there are syntax errors; remove old lint workflow
