cross-repo linting

[josh-chamberlain]

Context

We have a lot of repos and should probably lint them in similar ways.

• We see a lot of warnings and suggestions for formatting, which don't affect our ability to merge non-working code...we could have the linter make the commits for us
  • pre-commit linting on push
  • other considerations for this? times we should avoid it?

Requirements

• use something like super-linter supports ESLint and flake8
  • we could set up one config in this repo, and reference it in other repos

# example

name: Lint

on: [push, pull_request]

jobs:
  lint:
    uses: meta/.github/workflows/linter.yml@main
