Non-C/C++ Vulkan development

## Summary

In some surveys, we receive feedback from developers who want to use Vulkan in other languages, mostly Rust. You can easily use the C API from almost any language, and there are many popular, unofficial language bindings that allow you to use Vulkan in other languages.

You can use the Vulkan C API for learning Vulkan in any language. will add a good a basis for learning Vulkan in almost any language, most Vulkan concepts are language-independent.

## Proposed changes

We might want to add a short paragraph to the introduction explaining this. It might seem basic, but I believe some of the audience is not aware of it.

I would also consider adding a small paragraph about third-party tutorials, libraries and bindings for using Vulkan in other popular languages, but I am uncertain about this.

Start with the tutorial introduction and review the context of pull request #202. Add a short explanation that Vulkan's C API can be used from other languages, especially Rust, and decide whether third-party tutorials, libraries, or bindings belong there. Done means the introduction covers this clearly without expanding beyond the agreed scope.
