`SelectionPrompt` does not search on results of `UseConverter`

[snus-kin]

Information

• OS: MacOS (also tested on Windows)
• Version: 0.49.1
• Terminal: IntelliJ Rider Built-in Terminal (using Bash)

Describe the bug
Selection prompts which use UseConverter do not jump to the search (they do not use the mapped text as the search index).

To Reproduce

• Create a selection prompt
• Use .UseConverter()
• Search
• Observe that the result you have searched for is not jumped to

You can also search for the underlying object and observe that it is jumped to.

Example unit test that currently fails (where MyClass is just a class with a name parameter):

    [Fact]
    public void Should_Search_In_Remapped_Result()
    {

        // Given
        var console = new TestConsole();
        console.Profile.Capabilities.Interactive = true;
        console.EmitAnsiSequences();
        console.Input.PushText("2");
        console.Input.PushKey(ConsoleKey.Enter);
        var myObject = new List<MyClass>{ new() { name = "Item 1" }, new() {name = "Item 2"} };

        // When
        var prompt = new SelectionPrompt<MyClass>()
            .Title("Select one")
            .EnableSearch()
            .UseConverter(o => o.name)
            .AddChoices(myObject);
        var selection = prompt.Show(console);

        // Then
        selection.name.ShouldBe("Item 2");
    }

Expected behavior
SelectionPrompt should search based on the results of UseConverter and not on the underlying object remapped by it. (see test)

Some testing, this test works:

    [Fact]
    public void Should_Search_In_Remapped_Result()
    {

        // Given
        var console = new TestConsole();
        console.Profile.Capabilities.Interactive = true;
        console.EmitAnsiSequences();
        console.Input.PushText("2");
        console.Input.PushKey(ConsoleKey.Enter);

        var myObject = new List<Tuple<string, string>>
        {
            new ( "Value", "Item 1" ),
            new ( "Value", "Item 2" )
        };

        // When
        var prompt = new SelectionPrompt<Tuple<string, string>>()
            .Title("Select one")
            .EnableSearch()
            .UseConverter(o => o.Item2)
            .AddChoices(myObject);
        var selection = prompt.Show(console);

        // Then
        selection.Item2.ShouldBe("Item 2");
    }

Not sure if there's a better way of doing this, tried to refactor so the function is only called once per item. Will wait for a reply on this issue before creating a PR or anything.

Thanks for attempting to fix this, but we don't want to change the API. The UseConverter is used to get a representation, so we do not want to add an explicit representation when adding the item (optional or not) since this is what the converter is for. I will look into what is required to fix the search.

@snus-kin I've submitted a PR that should fix this. Will merge shortly

@snus-kin This is fixed and is now available in 0.49.2-preview.0.26
