[Snyk] Security upgrade react-scripts from 3.4.0 to 5.0.0

[impactyogi]

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

Snyk changed the following file(s):

• example/package.json
• example/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.

This is a significant major version upgrade from v3 to v5 that includes multiple breaking changes, most notably the upgrade to Webpack 5. This change removes automatic polyfills for Node.js core modules, which can break the build.

Highlights:

• Webpack 5 Polyfills Removed: react-scripts@5.0.0 uses Webpack 5, which no longer automatically provides browser polyfills for Node.js modules. If your project or any of its dependencies rely on modules like crypto, buffer, or stream, the build will fail until you provide manual fallbacks. [1, 4]
• Dependency & Runtime Upgrades: The upgrade drops support for Node.js 10 and 12, requiring Node 14 or higher. [1, 16] It also includes major version bumps for core dependencies like Jest (to v27), ESLint (to v8), and PostCSS (to v8), which may introduce new linting errors or require test updates. [1]

Recommendation: Before merging, carefully audit your application and its dependencies for reliance on Node.js polyfills. After upgrading, expect to fix build errors, update Jest snapshots, and resolve new ESLint violations.
