`manage_node_deps.py` was changed in https://chromium-review.googlesource.com/c/devtools/devtools-frontend/+/2259834 to add line endings at the end of the package.json file However, `npm run install-deps` was not rerun to add the line endings. To prevent future CLs that add deps to include the line ending changes, fix them in this CL.
