The env MEDIA_URL was missing in the frontend
Dockerfile. It is not necessary in our
running environment (staging / preprod ...) but it
is necessary if we want to run the frontend with
a different media url.
SW_DEACTIVATED was missing as well, we need to
deactivate the service worker in the frontend when
we test with Playwright.
We want to be able to brand our website (theme and logo)
at build time, we use the dsfr theme but
the german will use their own theme with their
own logo.
We will use a env var to set the theme,
depend the environment we will be able to
use different theme at build time.
