Documentation Changes

• Remove the extra trailing double quote (") after the refine-codemod command which causes the command to fail
• Update the example @refinedev/react-router version changes to ^1.0.1, as the current version (as of 12/2024) is 1.0.1 this will help prevent confusion when verifying the upgrade
