Subject: [PATCH] set PYTHONUTF8=1 for attestation step to fix encoding on
 Windows

pypi_attestations sign writes attestation JSON files using the Windows
default encoding (CP1252) rather than UTF-8, causing twine to fail with
a UnicodeDecodeError when reading them back. PYTHONUTF8=1 forces UTF-8
for all file I/O on Windows.
