Add a structured practice loop to the technical-interview links page

Hi Curriculum Team,

The technical-interview useful-links page currently lists resources, but it does not show learners how to turn reading into deliberate interview practice. I would like to add a short, beginner-friendly practice loop: explain one topic without notes, write a small example, test normal and edge cases, record the gaps, and repeat.

Proposed text for `org-cyf-guides/content/employability/interview/technical-interview-prep/useful-links/index.md`:

## Turn a resource into practice

Do not only read questions. Choose one JavaScript topic and use this loop:

1. Explain the topic without notes.
2. Write a small example and say what each line does.
3. Test one normal case and at least two edge cases.
4. Write down what you could not explain, then repeat the loop.

The [JavaScript interview preparation path](https://frontendatlas.com/guides/framework-prep/javascript-prep-path) groups topics such as async code, closures, state, and browser behaviour so you can choose what to practise next.

Disclosure: I maintain FrontendAtlas, so the linked resource is ours. The page is publicly accessible. The learning workflow is the main proposal; please leave out the link if it does not meet your resource policy.

Would this fit the employability guide? If so, I can prepare a small PR, follow the style guide, and verify the rendered preview.

Edit org-cyf-guides/content/employability/interview/technical-interview-prep/useful-links/index.md. Start by reviewing the surrounding page and the project style guide, then check whether the disclosed FrontendAtlas link meets the resource policy. Done means the beginner-friendly practice loop is included, any approved link is accurate, and the rendered preview is verified.
