Fix assignment of template field in __init__ in analyticdb_spark.py

[romsharon98]

related: #36484

removed the templated field because it's been run over in the constructor and has no meaning. (this can be cause an issue if someone will inherited from those classes).

fix:

AnalyticDBSparkSQLOperator's constructor lacks direct assignments for instance members corresponding to the following template fields (i.e., self.field_name = field_name or 
super.__init__(field_name=field_name, ...) ):
['spark_params']
AnalyticDBSparkSQLOperator's constructor contains invalid assignments to the following instance members that should be corresponding to template fields (i.e., self.field_name = field_name):
['self.spark_params']
AnalyticDBSparkBatchOperator's constructor lacks direct assignments for instance members corresponding to the following template fields (i.e., self.field_name = field_name or 
super.__init__(field_name=field_name, ...) ):
['spark_params']
AnalyticDBSparkBatchOperator's constructor contains invalid assignments to the following instance members that should be corresponding to template fields (i.e., self.field_name = field_name):
['self.spark_params']
