Include location in nginx config for logs specific directives (#3654)

Resolves #3652

# Description of Changes

Update docs nginx configuration to better support `spacetime logs
--follow` when self hosting configured to use ssl.

# API and ABI breaking changes

None

# Expected complexity level and risk

1

# Testing

I have added this location to my own nginx configuration and confirmed I
am able to `spacetime logs -s some-https-server <my-module> --follow`
and see logs immediately and continue following even if no log is
produced after 1 minute.
