Fix failing npm test command, add CI action to run tests

[roerohan]

Currently, the entire semantic release process has been set up. However, an essential check missing in merging PRs is to see if automated tests run properly.

At the moment, the automated tests are for the default react page. This must be modified, and action should be added to run the npm test command.
