As a Wikisource user, I want all issues to be consolidated on Phabricator, so that the team can more easily manage and discover issues in one place.
**Background:** We are currently managing WSexport issues both [[https://phabricator.wikimedia.org/project/board/3917/ | here on Phabricator]] and on Github at https://github.com/wsexport/tool/issues This is making it hard to triage issues and have a good overview of what needs to be worked on. I suggest we migrate all Github isses to Phabricator, and turn off issues on the GH repo. This task came out of the #commtech retro.
**Acceptance Criteria:**
* Copy all open issues to Phab (or merging into existing tasks)
* Update links in the code
* Update links on wikis
* Change the title of the Phab project (it already has `wsexport` as an alias)
