New contributor workflow: No test data loaded into `docker-compose` local server

## The problem

Following [this page on the recommended environment getting started steps](https://docs.gitcoin.co/mk_setup/), I was unable to get any of the test data loaded including grants, and bounties.

Steps to reproduce:

- On a new vm, running Ubuntu focal, confirm docker version:
```
vagrant@ubuntu-focal:~$ docker --version
Docker version 20.10.12, build e91ed57

vagrant@ubuntu-focal:~$ docker-compose --version
docker-compose version 1.25.0, build unknown
```

- Clone repo & execute copying `.env` step
```
vagrant@ubuntu-focal:~$ git clone git@github.com:gitcoinco/web.git
Cloning into 'web'...
...
vagrant@ubuntu-focal:~$ cd web
vagrant@ubuntu-focal:~/web$ cp app/app/local.env app/app/.env
```

- run `docker-compose` to bring up local server
```
vagrant@ubuntu-focal:~/web$ docker-compose up -d --build
...
```

- No grants


- No bounties


## Stuff I tried:
I thought running `make load_initial_data` would make a difference, but nothing, get the same results.

Poking around the Django admin console, it appears that the users were loaded correctly


but no data found in the other tables:


I didn't see anything in the build logs that would indicate problems with loading the data initially and I don't see any further steps in the setup guide. I'm probably missing something obvious. If so, maybe this is a good chance to update the contributor docs?

### System Info

This happened on both my local desktop running Pop_OS! 21.10 and a fresh Ubuntu Focal VM
