Get Wafv2 Web ACL freezes the terminal

### Describe the bug

Attempting to get a Wafv2 Web ACL makes the terminal freeze.

### Expected Behavior

Interactive mode displaying required parameters immediately when selecting the operation.

### Current Behavior

The terminal freezes when selecting the operation.

### Reproduction Steps

- Make sure the CLI is configured for interactive mode, I am setting the variable _AWS_CLI_AUTO_PROMPT_ to _on-partial_ in my terminal
- Start an interactive session by for example running "aws wafv2"
- Start typing "get-web-acl" and select it
- The terminal should freeze at this point

### Possible Solution

_No response_

### Additional Information/Context

Other get operations such as "aws lambda get-function" displays available parameters just fine. I assume something must be off with the config for get webacl.

### CLI version used

2.11.21

### Environment details (OS name and version, etc.)

macOS Big Sur, Version 11.7.6
