Volto production docker builds failure with webpack error

[arky]

Volto production builds fails in docker.

To Reproduce Steps to reproduce the behavior:

1. Checkout plone volto training github repo https://github.com/collective/training-deploy-project
2. Change directory to local root directory of the repo.
3. Initialize a new volto code base and use 'frontend' default addon name.
4. Change directory into 'frontend' and yarn install and yarn start
5. Build a new frontend container with 'make build-image)

Expected behavior Docker build fails with webpack module missing error. How docker builds succeed if you remove '--prod' entry in the dockerfile https://github.com/collective/training-deploy-project/blob/main/frontend/Dockerfile#L16

@ericof I had better luck with production builds with following command.

yarn install --frozen-lockfile --no-cache --production

[ericof]

I will test it as well
