RF: move codespell configuration into .codespellrc so could be used locally as well (#3958)

ATM configuration was embedded within the CI workflow but that makes impossible
to use  codespell  locally since the tool would not find those settings. I moved them
into .codespellrc  but then also removed codespell.yml workflow from skips, added .git and
in general makde it look for .dotfiles too
