Enable linking a suggestion to a phabricator ticket

Description

When users file suggestions for new collections, they want to be able to track the progress of that request as the maintainers go through their pipeline for trying to get a partnership with the suggested partner

Rationale

We need a way to link the suggestions to a Phabricator ticket so that users who visit the suggestion page can click through to see what the progress on that request

Phabricator Ticket

https://phabricator.wikimedia.org/T299883

How Has This Been Tested?

By going to the suggest collection page and clicking on the Phabricator ticket link.
