[Rust] Release 0.48.1

Fixed

• Missing required errors in evaluate() output for schemas with properties and a two-entry required array. #1220
• contentEncoding errors for invalid UTF-8 after decoding incorrectly had empty instance_path and schema_path.

Performance

• Faster code generation for #[jsonschema::validator] (~5% across benchmarked schemas), via aliasing repeated paths in the emitted code.
