Follow-up to https://github.com/discourse/discourse-data-explorer/pull/102. This is essentially a revert of that PR, the only difference is that the `.discourse-compatibility` file now pins the plugin to https://github.com/discourse/discourse-data-explorer/commit/60ffd4bc4d357b365cdb8a6764cec621f2edcf81 for sites ≤ `2.7.0.beta3`.
