Consider use UTF-8 by default for Azure CLI

### Describe the bug

I was reported a bug on StackOverflow: https://stackoverflow.com/q/78008939/910074

When I have to use `UTF-8` for my default console output encoding (`[Console]::OutputEncoding`), the Azure CLI unable to handle Chinese characters because Encoding issue. It cause either Chinese chars missing or produce messy code.

### Related command

`$(az account list -o json)`

`az account list -o json | jq '.'`

### Errors


### Issue script & Debug output

It's an encoding issue.

### Expected behavior

I expected Azure CLI can handle Chinese characters correctly.

Your CLI is up-to-date.

I have a workaround by now. Just edit `C:\Program Files\Microsoft SDKs\Azure\CLI2\wbin\az.cmd` file. Add `-X utf8` to the python arguments.
