Sometimes `sudo` interferes with `docker-compose up`

[KastanDay]

When trying to use this repo from scratch, I saw that using sudo caused problems, where non-sudo docker-compose -f docker-compose.yml -f docker-compose.extractors.yml up -d worked fine. Weird behavior when the images need to be pulled for the first time.

Looks like this issue is correlated with M1 macs: docker/compose#9560

From that thread ^^ it seems like sudo is not recommended on mac, but it is on linux.

TODO: update index.md to check platform and only use sudo on linux, not mac.
