Improve error handling in Google Sheets blocks

Fixes the deleted row count to use sorted_indices in GoogleSheetsDeleteRowsBlock. Adds validation for secondary sort column existence in GoogleSheetsSortBlock, raising a ValueError if not found. Enhances GoogleSheetsUpdateRowBlock to validate all column names before updating, raising a ValueError if any are missing.
