Found Pre-existing CI Build/Path Issue

Following up on the CI failures, I investigated further and found that the missing derpyramda.js module is part of the source code:
It is defined as a Node.js project in source/scripts/node/derpyramda/.

The test source/ports/py_port/test/test_simple.py (line ~63) tries to import from it.
The MODULE_NOT_FOUND error indicates this module is not being built or deployed correctly to the test environment in CI.

Conclusion Reinforced: My documentation-only PR does not affect the CMake build system or the deployment path of the derpyramda test module. The CI failures for both the Node.js module resolution and the Python segmentation fault are pre-existing infrastructure or flaky test issues.

Don't worry that is because those CIs are work in progress. Your PR is fine, I am merging it.
