Added support for new ARIA 1.3 accessibility attributes that enhance support for users with disabilities, particularly those using braille devices: - aria-braillelabel: Provides specific labels for braille device users - aria-brailleroledescription: Provides role descriptions for braille devices - aria-colindextext: Provides human-readable text alternatives for column indices - aria-rowindextext: Provides human-readable text alternatives for row indices These attributes were introduced in the ARIA 1.3 specification (First Public Working Draft, January 2024) and improve React's accessibility support by allowing developers to provide enhanced context for assistive technologies. Added comprehensive tests to verify that these new attributes are properly validated and don't trigger warnings when used correctly.
