Update rule-doc-generator-contracts nette/utils dependency

[gitomato]

Hello, I'm not sure where to post this issue.

This repository has a dependency on symplify/rule-doc-generator-contracts, but that repository is a readonly subset of the archived Symplify monorepo.

There is a pending change on main branch allowing nette/utils 4.0.

Could you tag that repository to enable nette/utils upgrade on symplify/coding-standard ?

Thanks for your work!
