Source all environment variables in order to match Next

See original GitHub issue

🐛 Bug Report

The library only loads environment variables when they’re prefixed with NEXT_PUBLIC_.

https://github.com/toomuchdesign/next-page-tester/blob/a483a65fd228587f16f2ced52909acc2b42d459d/src/setEnvVars.ts#L24-L26

However, this is different than Next’s behavior. These “private” environment variables are indeed made available to SSR and build functions, such as getStaticProps.

Reproduction

Simply require an environment variable without a NEXT_PUBLIC_ prefix in a getStaticProps function, for example. It will be undefined.

Expected behavior

In order to match Next and expected functionality, these variables should be available to build and server runtime functionality.

The issue affected only getStaticProps. It was an actual missing implementation detail 👍 Fixing with #197
