handle S3 "KeyTooLongError" as PathNotFoundError in storage

[syphar]

in sentry we are seeing a new error from S3:

Unhandled

unhandled error (KeyTooLongError)

ErrorMetadata

Error { code: "KeyTooLongError", message: "Your key is too long", s3_extended_request_id: "8hzp1Kv7cGOsjW3EUaqBxaI8krQbNJYFX1UZdb5DzKsKpHG7B1K9rvRATlrT/MHw3kPtIbLIn9fEdGUrm85/Uw==", aws_request_id: "16PF5FB54MZZ081Q" }

it happens when the path in the requested URL is too long, and IMO should be seen as the same as a 404 from S3.
