part 7e - "React/node-application security" references create-react-app

[bambery]

From: https://fullstackopen.com/en/part7/class_components_miscellaneous#react-node-application-security

Running npm audit fix --force would upgrade the library version but would also upgrade the library react-scripts and that would potentially break down the development environment. So we will leave the library upgrades for later...

Except this justification no longer makes sense, as react-scripts is a create-react-app library, and no longer used. There are 4 total references in this section to react-scripts that should be removed. I would submit a PR, but I don't know what the desired content/context is in the new vite world.
