Nothing works in the samples (tests)

Describe the bug

indexers, samples given, don't work.
https://github.com/Handlebars-Net/Handlebars.Net.Extension.Json/blob/main/source/Handlebars.Extension.Test/JsonTests.cs

        [Theory]
        [ClassData(typeof(EnvGenerator))]
        public void ArrayCount(IHandlebars handlebars)
        {
	        var model = JsonDocument.Parse("[{\"Key\": \"Key1\", \"Value\": \"Val1\"},{\"Key\": \"Key2\", \"Value\": \"Val2\"}]");

	        var source = "{{this.Count}} = {{this.Length}}";

	        var template = handlebars.Compile(source);

	        var output = template(model);

	        Assert.Equal("2 = 2", output);
        }
        

Count/Lenght don't do anything
Sample:

    [Theory]
        [ClassData(typeof(EnvGenerator))]
        public void ArrayIndexProperties(IHandlebars handlebars)
        {
            var model = JsonDocument.Parse("[\"Index0\", \"Index1\"]");

            var source = "{{@root.1}}";

            var template = handlebars.Compile(source);

            var output = template(model);

            Assert.Equal("Index1", output);
        }

        [Theory]
        [ClassData(typeof(EnvGenerator))]
        public void ArrayIndexPropertiesNested(IHandlebars handlebars)
        {
            var model = JsonDocument.Parse("[{}, {\"Items\": [\"Index0\", \"Index1\"]}]");

            var source = "{{@root.1.Items.1}}";

            var template = handlebars.Compile(source);

            var output = template(model);

            Assert.Equal("Index1", output);
        }

Count and indexer don't do anything (using 1 and 0)

If I remove 0 it works and shows the whole array.

Expected behavior:

to work?

Test to reproduce

var handlebars = Handlebars.Create();
handlebars.Configuration.UseJson();

//Handlebars testing, uncomment to see results
var handlebarsModel = JsonDocument.Parse(jsonContent);
//Test 1 iterate and test various properties
var testTemplate1 = "{{#each this.body.participants}} COUNT: {{this.Count}} LENGTH: {{this.length}} INDEX: {{@index}} ISFIRST: {{@first}} ISLAST: {{@last}} PARTICIPANT NAME:{{@value.name}} PARTICIPANT ROLE: {{@value.role}};{{/each}}";

//can be done also like
//var source = "{{#each this}}{{@key}}{{@value}}{{/each}}";

var compiledTemplate1 = handlebars.Compile(testTemplate1);

var resultTemplate1 = compiledTemplate1(handlebarsModel);

 //https://github.com/Handlebars-Net/Handlebars.Net.Extension.Json/blob/main/source/Handlebars.Extension.Test/JsonTests.cs
 //In the examples they use @root.0 but it doesn't work..... nor @root.0 and this.0 works to navigate elements
 //@root.body.participants and this.body.participants works, but not the indexer 0,1,2
 //var testTemplate2 = "{{@root.body.participants.0}}";
 //var testTemplate2 = "{{@root.body.participants.0.name}}";
 //var compiledTemplate2 = handlebars.Compile(testTemplate2);

 //var resultTemplate2 = compiledTemplate2(handlebarsModel);
