EIPW should warn if an otherwise valid EIP file is contained in a folder not named `EIPS`

The GitHub Action for eipw only checks files in the EIPS directory (because of the template, markdown in asset folders, etc.) You're suggesting that eipw should check all eip-*.md files regardless of where they are, be silent if they don't pass validation, but warn if they pass validation but aren't in EIPS/?

Yes, that's exactly what I'm suggesting.

Will be implemented in the review bot instead.
