BIT-PYTHON-2026-17084 stringprep.map_table_b2() deviates from RFC 3454 Table B.2

The "stringprep" module didn't process characters from RFC 3454 tables B.2 or B.3 correctly: the latest Unicode codepoint attributes were used instead of the specified Unicode 3.2.0. This behavior would cause mismatches when processing domain names using IDNA 2003 the "idna" codec and the intable...
