Remove the DEEP link on the IM page of the Catalogue of Surge Services

On the IM page of the Catalogue of Surge Services (https://go.ifrc.org/surge/catalogue/information-management), there is a link to DEEP in the Additional Resources section. DEEP no longer exists, and this link no longer works, so should be removed.
