Description

Describe the bug

We use the environment variables to set up among others, API url, base url, etc. But when launching the storybook it is unable to find the setup environment variables!

To Reproduce

Just setup and NextJS project with storybook, define any page or function to use with environment variables, create its story and run it.

Additional context

We are using Storybook as a workaround to test the pages with MSW, using the respective addon.

It could be fixed by applying this on the addon.

Research direction
Investigate the NextJS addon's configuration files, particularly how it loads environment variables. Look at the workaround suggested in the issue (https://www.rmkennedy.com/posts/storybook env vars) to understand the required changes. The fix may involve ensuring that environment variables are passed through to the Storybook build process. Review the addon's source code in `code/addons/nextjs` and the main Storybook configuration loading, and check the 21 comments for additional insights.
