feat: Codepen CDN referencing and adding font and logos

[martascorreia]

User Story

As a User of the Solid Design System, I would like to be able to edit the Codepen snippets with font, logos and theming incorporated, so that I can more easily see the final result while testing the components.

Suggested Solution

The theming has already been added here: #3045. In the same way theming was added, logos and fonts can also be passed to Codepen.

As an addition to this task, it is also required to do the migration from using packaged CDN references (e.g. https://solid-design-system.fe.union-investment.de/tokens/6.21.2/cdn/themes/ui-light/ui-light.css) to tools like https://cdn.jsdelivr.net (https://cdn.jsdelivr.net/npm/@solid-design-system/tokens@6.13.0/cdn/themes/ui-light/ui-light.css) or https://unpkg.com/ since the CDN will be decommissioned.
