Add --debug flag to help output

### Is this feature request related to a new or existing Amplify category?

_No response_

### Is this related to another service?

_No response_

### Describe the feature you'd like to request

Some commands in the amplify cli support an optional --debug flag which will output additional information as the command executes that could potentially assist customers. One customer noted that this would be good to have included in the help documentation as they were attempting to execute with a `-v` in the hopes for similar results.

### Describe the solution you'd like

Include --debug as a supported flag on relevant commands, and optionally aliasing -v as this is another common flag with the same purpose

### Describe alternatives you've considered

Inclusion in docs.amplify.aws would also assist with customers looking for this capability

### Additional context

_No response_

### Is this something that you'd be interested in working on?

- [ ] 👋 I may be able to implement this feature request

### Would this feature include a breaking change?

- [ ] ⚠️ This feature might incur a breaking change

Start by inventorying Amplify CLI commands that already support --debug and comparing their help output and documentation. Define which commands are relevant and whether -v should be an alias; the work is done when the supported flags are consistently exposed in help and the behavior is documented.
