fix orion environment not working

[ignazio-bovo]

Fixes the current orion environment not working when starting the playground
I have also removed the squid-archive services in favour of our new archive endpoint

Works well, but the default archive gateway on startup is the production chain which doesn't make sense. I think we should keep an archive + gateway in the setup. If we choose to run orion from this repo for the production chain then we set the CUSTOM_ARCHIVE_GATEWAY_URL env variable to https://archive.joystream.org/graphql

obviously this will only work when opening email from the machine. But I gather we would most likely disable email confirmation and notifications in a playground setup so thats fine.

@ignazio-bovo The CI check that is failing:
https://github.com/Joystream/joystream/actions/runs/6099420853/job/16551528071?pr=4857#step:12:16435

because it tries to use the adjacent docker-compose file docker-compose-no-bind-volumes.yml by first copying it over to docker-compose.yml

Please apply the same fixes to that as well.

A couple minor fixes needed of archive explorer config. Otherwise working nicely.

With so env variables now in the .env file and with some similarly named ones, i think in future we need to do a bit of refactoring to make it more manageable.

There is an identical SENDGRID_API_KEY variable below for the faucet.
perhaps we can prefix the one for orion with ORION_SENDGRID_API_KEY then pass that env variable in docker-compose environment section (so you don't have to modify orion code to expect a different variable name)

[mnaamani]

can we rename this file to orion-postgres.conf, there is another PR where I was planning to add a postgres.conf file for the query-node db. It makes sense to have two different conf files for each db instance.

I think the hostname is incorrect, (should it be orion_archive_db), also the correct port for the archive db ARCHIVE_DB_PORT is not used here.

I'm seeing connection error log for the explorer container:

2023-09-11 10:54:19 {"level":3,"time":1694415259620,"ns":"sqd:substrate-explorer","msg":"failed to connect to postgres://postgres@archive_db:5432/squid-archive","err":{"errno":-3008,"code":"ENOTFOUND","syscall":"getaddrinfo","hostname":"archive_db","stack":"Error: getaddrinfo ENOTFOUND archive_db\n    at GetAddrInfoReqWrap.onlookup [as oncomplete] (node:dns:109:26)"}}
2023-09-11 10:54:19 {"level":2,"time":1694415259730,"ns":"sqd:substrate-explorer","msg":"listening on port 3000"}

You need the DB_PORT also to be set for the explorer, and the renamed postgres.conf file needs to be adjusted in the docker-compose file for the orion-db service to match the new name:

    volumes:
      - orion-db-data:/var/lib/postgresql/data
      - ./orion-postgres.conf:/etc/postgresql/postgresql.conf

[mnaamani]

These need to be used in docker-compose to pass the expected env var name to orion like so:

environment:
      - SENDGRID_API_KEY=${ORION_SENDGRID_API_KEY}
      - SENDGRID_FROM_EMAIL=${ORION_SENDGRID_FROM_EMAIL}
