feat(errors): add error fingerprints for CockroachDB, YugabyteDB, DuckDB, Trino, OpenGauss, Doris, StarRocks

[jankesec]

Summary

This PR adds missing error message regex patterns to data/xml/errors.xml for DBMS forks already declared in lib/core/enums.py (FORK class):

• CockroachDB (PostgreSQL fork): CockroachDB.*?ERROR, pgwire/pgerror, crdb_internal\., version string check
• YugabyteDB (PostgreSQL fork): YugabyteDB.*?ERROR, org\.yb\., version string check
• OpenGauss (PostgreSQL fork): openGauss.*?ERROR, org\.opengauss\.util\.PSQLException
• DuckDB (SQLite fork): duckdb\.duckdb\.(Parser|Binder|Catalog|Conversion)Exception, org\.duckdb\.DuckDBException, Parser Error: syntax error at or near
• Trino (Presto fork): io\.trino\.jdbc, io\.trino\.spi\.
• Doris (MySQL fork): org\.apache\.doris\., version string check
• StarRocks (MySQL fork): com\.starrocks\., version string check

Verification & Testing

• Added unit tests in tests/test_html_parser_forks.py verifying all fork detections and kb.forkNote population.
• Ran full test suite: python3 -m unittest discover tests -> 2631 tests passed (0 failures).
• Ran smoke test: python3 sqlmap.py --smoke -> PASSED.
