NotHaveColumn assertion for data tables

### Background and motivation

As per the documentation https://fluentassertions.com/data/

Currently there is a HaveColumn assertion for data tables, but there is no NotHaveColumn

### API Proposal

this probably isn't right, but should give an indication:

```C#
public class DataTableAssertions
{
public AndConstraint NotHaveColumn(string columnName, string because = "", params object[] becauseArgs);
}
```

### API Usage

```C#
var table = new DataTable();
table.Should().NotHaveColumn("User")
```

### Alternative Designs
