[Fix][API] fix TaskDefinitionLog save error (#6246)

The reason is when saving the TaskDefinitionLog, the environmentCode field uses 'taskDefinition' which is NOT defined instead of 'taskDefinitionLog' defined in the 'foreach declaration'. so just change 'taskDefinition' to 'taskDefinitionLog' in 'TaskDefinitionLogMapper.xml'
