Add contributed tab to Vue version of Your work -> Projects

What does this MR do and why?

Related to #450200 (closed)

We are currently working on moving the Your work -> Projects page from HAML/vanilla JS to Vue. This will allow us to have UX parity across the product, implement filters more easily, and reduce technical debit.

This MR sets up the GraphQL query and renders the projects on the Contributed tab.

This MR does not implement

The following will be completed in follow-up issues/MRs:

• Tab counts
• Link delete modal to API (logic will be moved from organizations/shared/components/projects_view.vue#L171)
• Filtering and sorting
• Render projects in other tabs
• Empty states
