feat: make links customisable (navbar/dropdown)

[fadeev]

Right now items in the dropdown are not links. We need to make the dropdown customizable by our users.

Before implementing, propose the solution below. Probably, it's going to be a prop that a dev can set and we have it set by default to Starport websites/twitter in the template.

Hey @fadee, @marinhoarthur, As you already know, our component is not completely abstract and scalable to be customizable and reusable. I found a solution, and as already discussed, I will initiate a discussion about this solution.

This is already a working solution as I have implemented and tested it locally.
