Customer feedback | az webapp deploy | clarify `--acr-use-identity` parameter being enabled or disabled vs true or false

### Describe the bug

This GitHub issue is being moved from UUF [292320](https://dev.azure.com/msft-skilling/Content/_workitems/edit/292320).

### Summary
As this UUF does not provide the reference command, I'm guessing that the customer confusion is coming from `az webapp deploy` which has an `--acr-use-identity` parameter.

### Engineering request

1. Add information about the default property on all boolean parameter types in this command group.
2. Add more complex examples to `az webapp deploy`. There are 15 parameters and only 2 examples. Please see the [published reference guidelines](https://github.com/Azure/azure-cli/blob/dev/doc/reference_doc_guidelines.md#examples) for Azure CLI examples. For example, `Provide at least one example for every parameter. A single example can use multiple parameters, but a parameter that doesn't appear within an example code block often shows no usage statistics in Azure CLI reporting.`.

Verbatim:
--acr-use-identityEnable or disable pull image from acr use managed identity.Default value: FalseIt says, default false, so its assumd that you can set it to true or false, but that is not possible. So the default value should perhaps be "disabled" instead of false?"
