There is already an existing CODEOWNERS entry for /tools/Azure.Mcp.Tools.Workbooks/ at lines 237-241. This new entry creates a duplicate. You should either:

1. Update the existing entry (lines 237-241) to add @gardnerjr as an owner, or
2. Remove the existing entry and keep this new one

Additionally, note that the existing entry includes @microsoft/azure-mcp team reference, which is consistent with all other Azure MCP tool entries in this file but is missing from this new entry.

Suggested change

	/tools/Azure.Mcp.Tools.Workbooks/ @gardnerjr @matteing
	# ServiceLabel: %tools-Workbooks
	# ServiceOwners: @gardnerjr @matteing

The convention in this file is to have a blank line before each # PRLabel: comment to separate different tool entries. For consistency, add a blank line before line 268.
