Installation doc should mention "adduser sentry"

[tuxick]

Following https://docs.sentry.io/server/installation/python i ran into "sentry-worker.service: Failed to determine user credentials: No such process", which was a bit confusing. Turns out it means there's no system user 'sentry', running "adduser sentry" fixes this. Probably worth mentioning in documentation?

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you label it Status: Accepted, I will leave it alone ... forever!
