Fixed documentation typo's (#2127)

* Fixed typo at line 39

On this code example for the documentation there was a typo on the README.md file at line 39. There was an `;` where there should not be one.

The code that had the typo:

```cs
var tb = new TextInputBuilder()
    .WithLabel("Labeled")
    .WithCustomId("text_input")
    .WithStyle(TextInputStyle.Paragraph)
    .WithMinLength(6); // This ";" does not belong here.
    .WithMaxLength(42)
    .WithRequired(true)
    .WithPlaceholder("Consider this place held.");
```

* Changed `ExecuteAsync` to `ExecuteCommandAsync`

`_interactionService.ExecuteAsync(ctx, serviceProvider);` cannot be executed because the method `ExecuteAsync` does not exists.

* Changed `componBuild()` to `components.Build()`
