Align Ibis ci mysql driver with Ibis server image implementation

[douenergy]

Is your feature request related to a problem? Please describe.

Inconsistent MySQL driver implementations between CI environment and Ibis server image causing UTF-8 handling discrepancies.

Describe the solution you'd like

Standardize MySQL drivers across environments by updating the CI pipeline to use the same libmysqlclient-dev driver that's implemented in the Ibis server image. (like what we did in MSSQL)

Additional context

Local testing with the Ibis server image and Wren AI confirms proper UTF-8 compatibility. Aligning these implementations will prevent environment-specific bugs and reduce troubleshooting complexity.
