Update embed documentation

Ref #608

I checked back, you cannot explicitly copy stuff if it is mentioned in the .dockerignore. Docker will simply say that the file does not exist.

I will check for a different solution and adjust the documentation once i found something.

Alternatively, we could just add a warning in the docs asking the user to beware the .dockerignore file.
Using the git archive trick, it's easy for the end user to just remove .dockerignore from the generated directory.

The user could even add .dockerignore and other Docker related files in a .gitattributes file with the export-ignore attribute. This will prevent copying useless files into the standalone binary.

Also the composer dump-env prod command does not work without the composer install.

I mean we could do some little renaming and copy the .env files and vendor folder explicitly into the docker container but i think it is easier to maybe just mention, that the COPY . . command will ignore anything in the .dockerignore and one should adjust it to not ignore the files that we want?

Alternatively, we could move the

# Set proper environment variables
echo APP_ENV=prod > .env.local
echo APP_DEBUG=0 >> .env.local

# Remove the tests
rm -Rf tests/

# Install the dependencies
composer install --ignore-platform-reqs --no-dev -a

# Optimize .env
composer dump-env prod

part inside the static-build.Dockerfile.

Any opinions?

I generated the translations so maybe some native speaker should check them again ^^

I prefer this solution (when @crazywhalecc fix will be merged).

Thanks @bofalke!
