Add 'platform: linux/amd64' to postgis compose.yml

[petern48]

When running docker compose up -d on a mac, I get the following message since my machine is not amd64. I've been manually adding it to the file each time I need to use it, but it would be nice to just have it already there. It looks like amd64 is the only architecture they support, so I think it's safe to explicitly include for everyone.

Maybe there's a more proper way to handle this. I would just like to get it solved because it surely is inconvenient.

Sure! No idea why this doesn't show up for me. It is probably important when benchmarking (i.e., PostGIS will be super slow unless you're actually on x86).
