Quando tento dar o build retorna esse erro acima, não estou conseguindo criar as imagens e subir os container. :(

Fala galerinha, tenho um certo conhecimento em docker, então, consegui efetuar a correção do bug. Vou estar deixando o que eu fiz aqui para ajudar quem também estiver com problemas para "buildar" e executar o container. Primeiramente você pode deixar o 'DockerFile' assim

Troque a versão do python para 3.9.0 e também retire a linha

RUN pip install -r requirements.txt

Ficando assim o arquivo.

FROM python:3.9.0
ENV PYTHONUNBUFFERED 1
RUN mkdir /app
WORKDIR /app
ADD . /app/

Após isso, você pode estar se direcionando ao arquivo 'docker-compose.yml' e alterando a chave de command para a seguinte

      command: bash -c "pip install -r requirements.txt && python manage.py makemigrations && python manage.py migrate && python manage.py loaddata seed.json && python manage.py runserver 0.0.0.0:8000"

ou seja o arquivo ficará assim

version: '3.8'
services:
   web:
      build: .
      command: bash -c "pip install -r requirements.txt && python manage.py makemigrations && python manage.py migrate && python manage.py loaddata seed.json && python manage.py runserver 0.0.0.0:8000"
      volumes:
      - .:/app
      ports:
          - 8000:8000

O que fiz aqui foi apenas colocar o comando de execução do requirements direto na criação do container, e também alterei a versão do python. Tentei apenas alterar a versão e não funcionou, então fiz o comando em tempo de criação, e funcionou beleza. hehehe espero ajudar.
