SSM - parameter path and value changes are not updated in the stack.

There are two ways of resolving ssm parameters (as long as it isn't a secure parameter):
1. `ssm.StringParameter.valueForStringParameter`
2. `ssm.StringParameter.fromStringParameterAttributes`

They behave differently, but according to the documentation I would expect them to behave the same.

1. Test by changing paths
ie: change the SSM path from one deployment to the next.
Retrieving by value does what I expect - it updates values when the path changes.
Retrieving by attributes does not. The value in the stack will not change.

2. Test by changing values
it doesn't matter what we change, the values in the stack do not change.

### Reproduction Steps

https://github.com/brettswift/cdk-ssm-test

follow the README.md

shell scripts are there to demonstrate everything.

### Environment

- **CLI Version :**1.36.1
- **Framework Version:**
- **OS :**OSX
- **Language :**typescript

This is :bug: Bug Report

Start with the linked reproduction's README.md and shell scripts, then compare ssm.StringParameter.valueForStringParameter with ssm.StringParameter.fromStringParameterAttributes. Reproduce deployments with changed paths and values; done means both approaches update the stack consistently when the referenced SSM parameter changes.
