Update dependency nth-check to 2.0.1 [security]

Editor assessment

The subject names nth-check, gives the target version, and adds the security marker, which tells the reader the update closes a vulnerability, real motivation in a few characters. The chore type and deps scope fit, and the appended PR reference is well formed. No body appears, which is acceptable because the security flag already conveys the why; a link to the advisory would have been ideal but is not required. The Co-authored-by trailer crediting Renovate Bot is well-formed attribution. Style is clean: imperative, unperioded, appropriately sized. A complete, honest maintenance message with nothing misleading in it.
