fix(tabsContext.tsx): handle error message properly when saving changes in the tabs provider

The error handling in the tabs provider has been improved to display a more meaningful error message when there is an error while saving changes. Instead of directly assigning the error to the `setErrorData` state variable, the error message is now wrapped in an object with a title and a list of error messages. This change ensures that the error message is displayed consistently and provides better context to the user.
