[Feature Request] Support Direct Appending to Google Sheets

Direct appending to Google Sheets is not supported by the available tools.

🚀 Description

The existing Google Sheets capabilities in the Gemini CLI Workspace extension currently lack support for directly appending data (e.g., a new row) to a Google Sheet. The current functionality is primarily focused on querying and, in some cases, creating or overwriting content.

Adding a dedicated "append" functionality would significantly enhance the utility of the Google Sheets tool, especially for tasks involving logging, tracking, or collecting data from command-line interactions.

💡 Proposed Solution

Enhance the Google Sheets tool to include a command or mechanism that supports appending a new row of data to a specified Google Sheet, similar to the functionality available in the Google Sheets API's append methods.

Start by inspecting the existing Google Sheets tool and its current querying, creating, and overwriting capabilities. Compare its interface with the Google Sheets API append methods, then define the command or mechanism needed to append a new row to a specified sheet and verify that command-line logging and data collection work as intended.
