In order to switch `clippy::uninlined_format_args` from pedantic to style, all existing tests must not raise a warning. I did not want to change the actual tests, so this is a relatively minor change that: * add `#![allow(clippy::uninlined_format_args)]` where needed * normalizes all allow/deny/warn attributes * all allow attributes are grouped together * sorted alphabetically * the `clippy::*` attributes are listed separate from the other ones. * deny and warn attributes are listed before the allowed ones changelog: none
