• This change simplifies the certificate management in the JDBC driver.

Summary

Add Global Certificate to Enhance Connection Stability with Tableau

Description

This pull request addresses a recent issue where customers experienced connection problems using Tableau Desktop to connect to clusters authenticated with the new rds-ca-rsa2048-g1 CA certificate. To resolve this, the following changes have been implemented in the JDBC driver repository:

• Global Certificate Addition: Introduced global-bundle.pem to the default certificate list. This bundle includes the latest CA certificates, ensuring broader compatibility and trust chain completeness.
• Redundancy Removal: Eliminated rds-ca-2019-root.pem from the certificate list. This certificate is redundant as its contents are already included in the global-bundle.pem, streamlining the certificate management process.

do we need to remove rds-ca-2019-root.pem? why not just add the global file rather than replacing the old one? my main worry is that this may break connections for people relying on rds-ca-2019-root.pem
