[Snyk] Security upgrade react-scripts from 1.0.11 to 4.0.0

[saurabharch]

Snyk has created this PR to fix 1 vulnerabilities in the yarn dependencies of this project.

Snyk changed the following file(s):

• fixtures/attribute-behavior/package.json
• fixtures/attribute-behavior/yarn.lock

Note for zero-installs users

If you are using the Yarn feature zero-installs that was introduced in Yarn V2, note that this PR does not update the .yarn/cache/ directory meaning this code cannot be pulled and immediately developed on as one would expect for a zero-install project - you will need to run yarn to update the contents of the ./yarn/cache directory.
If you are not using zero-install you can ignore this as your flow should likely be unchanged.

Code Review

This pull request, automatically generated by Snyk, upgrades react-scripts from 1.0.11 to 4.0.0 to fix a security vulnerability. While this addresses the security issue, this is a major version upgrade that introduces a critical breaking change. The new version of react-scripts has a peer dependency on react@^17.0.0, but the project is still using react@^15.6.1. This will cause the application to fail. I've added a critical comment with details on how to resolve this by also upgrading react and react-dom.

[gemini-code-assist]

Upgrading react-scripts to version 4.0.0 is a major version jump that introduces breaking changes. Specifically, react-scripts@4.0.0 requires react@^17.0.0 and react-dom@^17.0.0 as peer dependencies.

The current package.json specifies react@^15.6.1 and react-dom@^15.6.1. This mismatch will likely cause peer dependency conflicts and may break the application.

To resolve this, you should also upgrade react and react-dom to a compatible version, for example ^17.0.0.

"dependencies": {
  ...
  "react": "^17.0.0",
  "react-dom": "^17.0.0",
  "react-scripts": "4.0.0",
