[I] [C#] ArrowArrayConcatenator doesn't handle non-zero offsets [arrow]

["adamreeve (via GitHub)" <gi...@apache.org>]

adamreeve opened a new issue, #41164:
URL: https://github.com/apache/arrow/issues/41164

   ### Describe the bug, including details regarding any error messages, version, and platform.
   
   Example unit test to reproduce:
   
   ```c#
   [Fact]
   public void TestConcatenateSlicedArrays()
   {
       Int32Array array0 = new Int32Array.Builder()
           .Append(new []{0, 1, 2})
           .AppendNull()
           .Append(new []{3, 4})
           .Build();
       Int32Array array1 = new Int32Array.Builder()
           .Append(new []{5, 6})
           .AppendNull()
           .Append(new [] {7, 8, 9})
           .Build();
   
       var concatenated = ArrowArrayConcatenator.Concatenate(new[]
       {
           ArrowArrayFactory.Slice(array0, 2, 3),
           ArrowArrayFactory.Slice(array1, 2, 3),
       });
   
       var expected = new Int32Array.Builder()
           .Append(2).AppendNull().Append(3)
           .AppendNull().Append(new[] { 7, 8 })
           .Build();
   
       Assert.Equal(expected, (IReadOnlyList<int?>)concatenated);
   }
   ```
   
   This fails with:
   ```
   Assert.Equal() Failure: Collections differ
              ↓ (pos 0)
   Expected: [2, null, 3, null, 7, ···]
   Actual:   [0, 1, 2, 5, 6, ···]
              ↑ (pos 0)
   ```
