[Wave Collect][Xero] Display error messages for Xero Import page

[lakchote]

Problem

We do not display meaningful error messages to the user for the Xero import page.

We only display the RBR indicator.

Solution

Display meaningful error messages to the user, just like we did in XeroExportConfigurationPage.

Note: you'll need to use the errorText property, please see https://github.com/Expensify/App/pull/41670/files#diff-e66a522b9cabb71f5418bb119bae86d49f12cc8f7da039acc4ff3c42991cd25fR29
