disableScc option is missing from no-cycle docs

[soryy708]

#2998 introduces a disableScc option to the no-cycle rule, but there's no reference to it in the rule's docs at https://github.com/import-js/eslint-plugin-import/blob/f72f2072f4245f2c3494816d7c14352fc9e07c0a/docs/rules/no-cycle.md

It's an error of omission, and we need to add it to the docs, so that users know about the escape hatch and what it does, without digging through issues/PRs about it.
