[Feature] Contribution page refactor and redesign

[Queen-codes]

Problem

The contribution page, along with other pages in this section of the open-source website, does not fully align with the latest version and features of the Vocabulary design system. To ensure consistency across all ancillary websites and maintain alignment with the design system, a code refactor is necessary.

Description

This redesign will update the page to incorporate Vocabulary’s latest components and styling, ensuring a smooth and unified user experience that mirrors the overall look and feel of the design system.
