Maintenance: use cached node_modules in integration tests workflow

[dreamorosi]

Summary

In a recent PR we modified the way in which the packages in the workspace are installed and built. In doing so I forgot to update one of the workflows that is in charge of running the integration tests, which due to this misconfiguration now fails consistently.

Why is this needed?

So that we are able to run the integration tests in our CI.

Which area does this relate to?

Automation, Tests

Solution

No response
