Add pre-commit, format all files, and add justfile

[sarayourfriend]

Fixes

Fixes #193 by @sarayourfriend
Fixes #187 by @sarayourfriend

Description

Adds pre-commit using the same configuration as the openverse-catalog with some modifications to ignore rules in certain files that were problematic.

Also adds a justfile to make docker stuff easier.

Technical details

I had to add some noqa comments for long strings (I wish flake8 would ignore strings...)

I also added .flake8 that mirrors the pre-commit configuration for flake8 so that editor integration will work

Tests

Checkout the branch and run just install then just lint and ensure that there are no errors reported.

I missed 'just' when coming from the catalog repository :) Thank you for improving DX!

@sarayourfriend this PR does not update the README.md file in the root? #201 had that updated to match the just commands.

[sarayourfriend]

@dhruvkb whoops, I missed that when moving things over to this branch, I'll update the README now. Thanks for catching that!
