• scripts/bw-compatibility-test/.env - Test configuration file updating LND base version for backward compatibility tests

Analysis

This PR updates the base LND version used in backward compatibility testing from v0.18.5-beta to what appears to be a newer version. This change:

• Only affects test infrastructure, not production code
• Is confined to a single configuration file in the scripts/ directory
• Has minimal lines changed (1 addition, 1 deletion)
• Poses no risk to core LND functionality

According to the severity classification rules, changes to scripts/* files fall under LOW severity, requiring only best-effort review. This is a routine test configuration update that can be merged with minimal scrutiny.
