Updates to WMDE MR template to account for checks/tests
This is a quick commit to update the MR template I've made for WMDE's work in the repo. Of note:
- It adds a tests section for the outputs of the tests that the contributor should run on their local database
- It adds a checklist item to make sure that all tables that the DAG jobs interact with are in HDFS (this was the reason why the DAG was originally failing)
Commits are only to /wmde, so I'll merge without review once tests pass.
Thanks!
