xarchiver can't open tar files created with this library

[I-Katie]

Describe the bug

The .tar files created with the library can be opened with 7zip, they can be extracted with "tar -xf" but the linux program xarchiver (default with some low memory graphical instalations - in my case debian with xfce) says that the archive format is not recognized.
Another place where xarchiver is installed by default is the raspberry pi debian instalation.

Reproduction Code

No response

Steps to reproduce

Simplest example I can come up with:

using FileStream os = new FileStream("test.tar", FileMode.Create);
using TarOutputStream tar = new TarOutputStream(os);

byte[] data = Encoding.UTF8.GetBytes("my text contents");

TarEntry entry = TarEntry.CreateTarEntry("myfile.txt");
entry.Size = data.Length;

tar.PutNextEntry(entry);

tar.Write(data);

tar.CloseEntry();

Expected behavior

The archive should be opened normally as it does in other applications.

Operating System

Linux

Framework Version

.NET 6

Additional context

There is a chance that xarchiver is just bad considering other software opens the archive.
But then again xarchiver opens tar archives made with other software.
