Fix broken Wiki Page History
This MR fixes the broken Page History on the Wiki pages. It turns out WikiHelper did not allow users to view different versions due to its omitting of query string parameters, which was necessary to specify different version_id parameters. Instead of this hacky approach, use manually-specified wildcard routes that match the ID field properly for slashes.
