To do this, we had to move the text where we add the links away from the i18n
string list since Hugo does not support using shortcodes (e.g. for links) in
there.

Also added a new param that points to the docs page that explains our
contribution process (we'll reuse this new param in a later commit for the
development/contributing section of nest)

Ran dev-server.sh and verified the content looks as intended and links worked
