Building the app with Docker creates a lot of volumes

[johannalaitila]

There are a lot Docker volumes being created when building the app. Investigate why this is and if it could be reduced. Also, a lot if images are being created, so same issue there.

@TrixterTheTux if I remember correctly, were you thinking that potentially node modules are being copied to a new volume every time the app is built?

Note for self - might be related to this:

docker/compose#1487

we use docker compose up currently

I suspect the cause is

voting-advice-application/backend/vaa-strapi/docker-compose.dev.yml

Line 34 in a34418f

- /opt/node_modules

with similar behavior inside the frontend compose, so what happens is that we create an unnamed volume each time the environment gets setup (due to my previous changes of --force-recreate, which happens to increase the frequency of this becoming an issue).
