Automated Spring Boot Version Update

This PR updates the Spring Boot version matrices in our test workflows based on the latest available versions.

Changes Made:

Spring Boot 2.x: ['2.1.0', '2.2.5', '2.4.13', '2.5.15', '2.6.15', '2.7.0', '2.7.18'] -> ['2.1.0', '2.2.5', '2.4.13', '2.5.15', '2.6.15', '2.7.18'] Spring Boot 3.x: ['3.0.0', '3.2.10', '3.3.5', '3.4.5', '3.5.6'] -> ['3.0.0', '3.1.12', '3.2.12', '3.3.13', '3.4.10', '3.5.6']

Update Strategy:

• Patch updates: Updated to latest patch version of existing minor versions
• New minor versions: Added new minor versions and removed second oldest (keeping minimum supported)
• Minimum version preserved: Always keeps the minimum supported version for compatibility testing

This ensures our CI tests stay current with Spring Boot releases while maintaining coverage of older versions that users may still be using.
