chore(workflows): add debug step for SQL Server password presence

This update introduces a new step in the workflow to check for the presence of the SQL Server administrator password. This helps ensure that the password is set before proceeding with the workflow.

- Added a debug step to verify if the SQLHELPER_SQL_PASSWORD secret is empty or present.
