SF-3661 Notify user when training data file format is invalid

[RaymondLuong3]

This PR will detect if a training data file contains rows that are invalid. Rows must have two columns of data. When a row contains fewer than 2 columns of data, the file will be rejected and the user is notified to check their data. If a row is blank, it will be skipped over.

test/SIL.XForge.Scripture.Tests/Services/TrainingDataServiceTests.cs line 603 at r1 (raw file):

        text = text.TrimEnd(); // Remove trailing new lines
        text = text.Replace("\r\n", " "); // Handle newlines in both linux and windows environments
        text = text.Replace("\n", " ");

When I used Environment.NewLine it was working locally and detecting the NewLine convention, but when this was run on GHA the excel file NewLine came back with the windows convention. I chose to just do a replace so it will be more robust.

Code quote:

        text = text.Replace("\r\n", " "); // Handle newlines in both linux and windows environments
        text = text.Replace("\n", " ");
