Cannot Move a readonly file

[patiqs]

Describe the bug
File.Move behavior is different in MockFileSystem and physical FileSystem.

To Reproduce
The test below is green with real FileSystem, but MockFileSystem throws System.UnauthorizedAccessException : Access to the path 'C:\any.txt' is denied.

 [Test]
 public void Move_a_readonly_file()
 {
 //arrange
 //IFileSystem fileSystem = new FileSystem();
 IFileSystem fileSystem = new MockFileSystem();
 var file = "any.txt";
 fileSystem.File.WriteAllText(file, "foo");

 //act
 fileSystem.File.SetAttributes(file, FileAttributes.ReadOnly); 
 fileSystem.File.Move(file, file+".moved");

 //assert
 Assert.That(fileSystem.File.Exists(file+".moved"));
 Assert.That(fileSystem.File.Exists(file), Is.False);
 }

Additional context
Tested with
Dotnet SDK: 8.0.404
Package I use:
TargetFramework: net48
Windows I use: Windows11 Ver:10.0.22631 Build 22631

Yes, you are right, this is indeed a bug!
If you want, I would be happy to accept a PR.

Alternatively you could use the alternative testing library Testably.Abstractions, which uses the same IFileSystem interface and has implemented the behaviour with moving a readonly file correctly.

This is addressed in release v22.0.11.
