[BUG] not able to add Workflow descriptions as parm to initialise BF

[ravishikhar]

Describe the bug
current initializations does not get initialised with descriptions as parm

the Workflow class doesn't accept a description parameter. Looking at the example from the Brickflow repository, the valid parameters for Workflow.init() include the workflow name, default_cluster, tags, common_task_parameters, and schedule_quartz_expression, but not description.
