Consider standardizing race_and_ethnicity vs race

right now, ACS and CDC_COVID use race, and most (all?) other sources we use race_and_ethnicity when referencing the non-user facing demographic breakdown. This inconsistency has added unneeded complexity to our codebase and many bugs and delays.

We should standardize; race is shorter and easier for future devs, race_and_ethnicity is more accurate since Hispanic is not really a race although we treat it as such by listing it alongside the other races.

Changing ACS and COVID would be fewer pipelines to change, however those are by far our longest running and most prone to break pipelines right now.

We should discuss
