Description

This PR does two things:

1. Do not filter locations with a population of zero
   We’ve been filtering out locations with a population of zero so we do not bloat the dataset too much. This seems to have the potential for false positives and we’ve received a report that a user could not enter their populated location. I checked and GeoNames does not list a population. Even though I’ve contributed the population number from the latest 2020 US Census to that location and this would already fix the issue for the certain location chances are high that this will be the only instance — so let’s better include those locations.

2. Reduce filesize of locationAutocompleteData.json
   The original filesize of the locations JSON we generate was 4.4 MB. When including all the locations with no entered population the size grew to ~22 MB. Just by excluding info we do not necessarily need for the location autosuggestion shrunk it to ~12 MB and with the additional shorting of the key names we are now at ~8 MB — at this size the LocationAutocompleteInput is still very responsive and seems to work well.

How to test

1. Navigate to /user/welcome to the “Enter info” step.
2. Search for the previously missing location mentioned in MNTOR-2913.
