Improve example for env vars in API docs

This was added in e41de3e631,
but can be a bit confusing due to the "outer" brackets
being for JSON, and the "inner" brackets to indicate
optional values.

During review of that change, this alternative
format was suggested.

Updating the example to use the format that was discussed
during review :)
