Downgrade clippy::allow_attributes and clippy::allow_attributes_without_reason to warn (#17320)
# Objective
I realized that setting these to `deny` may have been a little
aggressive - especially since we upgrade warnings to denies in CI.

## Solution
Downgrades these lints to `warn`, so that compiles can work locally. CI
will still treat these as denies.

//! Accessibility for Bevy
//!
//! As of Bevy version 0.15 `accesskit` is no longer re-exported from this crate.
//!
//! If you need to use `accesskit`, you will need to add it as a separate dependency in your `Cargo.toml`.
//!
//! Make sure to use the same version of `accesskit` as Bevy.
