Pull request overview

Removes the crate-level clippy::missing_safety_doc expectation in bumpalo_alloc.rs by updating the Alloc trait docs to include an explicit safety section, aligning the file with Clippy’s safety-doc requirements.

Changes:

• Drop #![expect(clippy::missing_safety_doc, ...)] and keep only clippy::undocumented_unsafe_blocks.
• Rename the Alloc trait documentation section from “Unsafety” to a safety section heading.
