Update flake8.json

This is just whitespace changes from https://github.com/TrueBrain/actions-flake8/blob/3a6da6285a2f3758f92df1917dbbc84c285c0378/action/flake8-matcher.json

The jsons here are intentionally indented by jq, even though it means divergence from the original source.

(I'll look at your other PRs once I get back from vacation in a couple weeks.)

Ah fair enough. Where I started with this, when I saw it differ, was wondering if it was out of date. Maybe this should be a separate issue, but it would be good if there was a system or process to keep these files in sync (Git submodules or just wget or whatever).

Thanks, no real rush.

That would be nice indeed, something like a periodic GitHub Action or something. I'm a bit worried that the problem matchers themselves won't change very often, whereas their location and the means to extract them from a possibly more complex json (like https://github.com/microsoft/vscode-cpptools/blob/a8285cbc0efb5b09c2d2229b0e0772dcb3b602df/Extension/package.json) will change more often, requiring more maintenance than it's worth. :-/
