Should we add build tests?

Build tests could in theory be implemented by using:

• different configs for tests that will be used to build exampleSite by running an npm script.
• Cloning different test repos to temporary directory and trying to build them by running an npm script.
• profiling of builds? (not sure if this makes sense)
• ...

These tests could be a bash script that just fails if any build fails.
This could be used in CI/CD and might prevent mistakes like mine that was mentioned in #2315 . I am sorry that I didn't think if testing this case btw.

I'll wait a few days and then come up with a PR or some other solution. Any feedback is welcome!

This could also be done in a separate repo that is added as a submodule, but @nunocoracao should probably have that test repo in his github account to avoid external submodules. This would help with repo size (#980).

Update: I've had a lot of other things on my mind recently, but I have a few good ideas of how this could be implemented and will implement them over time. Don't expect anything over the next month though :)
