Better filter and sort validation error handling

Main contributions

• Fix filter and sort validation error handling by @arthurio in Fix filter and sort validation error handling #207
• Add filter validation errors by @arthurio in Add filter validation errors #208

⚠️ Breaking change

This change affects the content of detail in the error response (not the response code itself). Instead of a string, the content of detail is now a list, e.g.: {'detail': [{'loc': ['query', 'bogus_filter'], 'msg': 'field required', 'type': 'value_error.missing'}]}. Make sure to update your error handlers accordingly!

Full Changelog: v0.5.0...v0.5.1
