feat: remove directory page links

[huwshimi]

Done

• Remove links to the canonical.com/projects/directory page.

QA

• Go to /legal/contributors and check that there are no links to the directory page in the first two paragraphs on the page (under the Canonical contributor licence agreement heading).
• Go to /legal/contributors/faq and check that there is no "Related content" box on the right hand side of the page, and that there is no "What if I have other questions?" at the end of the FAQ.
