ZKF-1446 Delete Out-Of-Gas Utility From Landing Page

### 🗒️ Business Requirements We need to delete Out-Of-Gas utility from drop-down from our landing page, so that users can't access this app anymore. It's useless because we'll fix this problem in future releases and will subsidise this transactions from our side.  ### ✅ Acceptance Criterias * [ ] Button "Solution for Out-of-gas issue" is absent in zkTools dropdown on zksync.io
