SUSE: 2025:20346-1 moderate: python311 update for critical issues

## This update for python311 fixes the following issues: * Updated to 3.11.12: * gh-131809: Updated bundled libexpat to 2.7.1 * gh-131261: Upgraded to libexpat 2.7.0 * CVE-2025-0938: Fixed functions `urllib.parse.urlsplit` and `urlparse` accepting domain names including square brackets (bsc#1236705) * gh-121284: Fixed bug in the folding of rfc2047 encoded-words when flattening an email message using a modern email policy. Previously when an encoded- word was too long for a line, it would be decoded, split across lines, and re-encoded. But commas and other special characters in the original text could be left unencoded and unquoted. This could theoretically be used to spoof header lines using a carefully constructed encoded-word if the resulting rendered email was transmitted or re-parsed.
