Ignore E203 in flake8

[surchs]

flake8 causes false positives of E203 (https://www.flake8rules.com/rules/E203.html) in certain cases

• https://results.pre-commit.ci/run/github/492977702/1714354140.xJpZ6dOpTvCvXJfHOZrTxA
• Does not comply with E203 from pep8 psf/black#315
• E203: False positive "whitespace before ':' " on list slice. PyCQA/pycodestyle#373

Since black handles this correctly (afaict), let's ignore rule 203 and get the linters to calm down a bit

This will also let us merge neurobagel/bagel-cli#297

One weird aspect is that I haven't been able to reproduce these false positives from flake8 locally. I.e. they only seem to happen as part of the pre-commit CI run

Can we close this since neurobagel/bagel-cli#300 is merged?

[alyssadai]

Ignore rule needs to be added to all repos where pre-commit-CI is set up

[surchs]

is there going to be enough overlap on the ignore rules to sync them to all (python) repos? I would assume so

[surchs]

There may not be enough overlap to just sync .precomit-config across all python repos. Let's revisit this issue when the E203 error pops up again. Likely at that point we would address it more generally by making the python repo setup consistent across our repos. That would be more of a maintenance milestone probably
