[Reference feedback]: Need acceptable values for `--resource` arg on `az rest` command

### Type of issue

Other (describe below)

### Reference command name

az rest

### Feedback

First, thanks for this excellent cli extension.
I am highly using azure cli for purpose about Azure Devops operations. For our one of requirement, I need to compare two branches of a repo with `az repos` but it hasn't any command for that. Then I tried to rest API of repo diffs via `az rest` command but I cannot succeed because of missed `--resource` argument. After hours, thanks to Copilot, I found the correct resource argument for dev.azure.com as `--resource "499b84ac-1321-427f-aa17-267ca6975798"`.
I think that `az rest` can use on very wide area but the documentation limits us.
