Document behaviour of lint cli args after `--` about redocly-cli

Thanks @collinsauve I think your usage is the right way to use the -- command. I'm going to close this issue since it's both familiar and also from an upstream repository, so I don't think there's further action for us to take.

Thanks for the confirmation that this is expected behavior. My primary concern was that I was relying on something unsupported.

Unfortunately I also don't see this in yargs docs. I used this only because, as you say it is a common pattern. Not going to push too hard on getting it documented now that it is confirmed here.

Thank you!

Hi @collinsauve! The behaviour is not specific to Redocly CLI, it's how yargs (which is used as the arguments processor here) handles the input. I'm not sure we need to document that though, since the behaviour is pretty common.
