The "Stream Audio" tab stops working after a stack update when AssistantWakePhraseRegEx is modified

[rstrahan]

Describe the bug
The "Stream Audio" tab stops working after a stack update when AssistantWakePhraseRegEx is modified. It does not display disclaimer, and then asserts that the websocket server is not enabled.

To Reproduce
Steps to reproduce the behavior:

1. Update LMA stack, and change the value of the AsistantWakePhrase parameter
2. After stack is updated, try using the LMA Stream Audio tab.

Expected behavior
Stream Audio tab should display disclaimer, and start streaming.

Screenshots

Additional context
Root cause: Updating AsistantWakePhrase parameter causes SSM Param CFN-LMASettingsParameter value to be replaced, overwriting the WSEndpoint and AssistantWakePhraseRegEx setting. The customer resource Lambda UpdateWSEndpointSettingsExec does not get re-run since none of its properties have changed, so the values never get re-added to the replaced SSM param.
