Expected Behaviour

Changing the value of daily_memory_time_quota should update the value of "Daily Usage Quota (GB-Sec)".

Actual Behaviour

Changing the value of daily_memory_time_quota has no effect. It is set correctly when a resource is created but not updated if the value is changed.

Steps to Reproduce

1. Create a linux function app with daily_memory_time_quota set to 1000
2. run terraform apply
3. Update the value of daily_memory_time_quota to 2000
4. run terraform apply
