Default parameter value ignored when parameter has previously been overridden

### Description:

If I were to deploy a SAM template to AWS while overriding a default parameter value, and then re-deploy the same template without overriding that parameter value, the default parameter value specified in the template is ignored and the previous override value is still used. This results in an error because the changeset says there are no changes to deploy.

It is possible to explicitly override the parameter value again, but it's not obvious that this is required, and if the change was part of a larger change this unexpected behaviour would likely be missed.

### Steps to reproduce:

Using the template and function below, build and deploy the SAM application.

In this case, a `schedule` event on a function creates an EventBridge rule, and the value of the `State` property is set by referencing the `ScheduleState` parameter. The default for the parameter value is `DISABLED`.

Using the steps below you can see that after the `ScheduleState` parameter is overridden when deploying the SAM application, the same value is unexpectedly used when re-deploying without overriding the `ScheduleState` parameter, rather than the default parameter value.

```shell
foo@bar:~$ sam build -u
foo@bar:~$ sam deploy --parameter-overrides ScheduleState=ENABLED
# EventBridge rule is enabled.
foo@bar:~$ sam deploy
# EventBridge rule is still enabled, default value of ScheduleState is not used.
foo@bar:~$ sam deploy --parameter-overrides ScheduleState=DISABLED
# EventBridge rule is disabled.
```

### Expected result:

I would expect the default value of the `ScheduleState` parameter to be used when deploying the SAM application without explicitly overriding that parameter, rather then the previous override value that has been set.

Basically, the observed behaviour is inconsistent, because upon deployment of the SAM application the user wouldn't necessarily know which of the following scenarios is true. Either...
- The default parameter value would not have been previously overridden so that value will be used.
- The default parameter value has been overridden, so that value will be used and may differ from the default value.

### Additional environment details (Ex: Windows, Mac, Amazon Linux etc)

1. OS: Ubuntu 22.04
2. SAM version: 1.55.0
3. AWS region: us-east-1
