Add Sources and Search Guide pages to the new header

[obulat]

Problem

The new header/footer navbar is missing the Sources and Search guide pages. The pages are already available in the /pages directory, they just need to be added to the use-pages composable.

Description

We need to add the pages here, between the Licenses and Get involved pages:

openverse-frontend/src/composables/use-pages.ts
