Code Review

This pull request, automatically generated by Snyk, aims to fix a security vulnerability by upgrading several dependencies. However, the proposed upgrades are all major version bumps for key packages like eslint, jest, and postcss-loader. These new versions contain significant breaking changes that are incompatible with the existing project configuration, which is based on an older version of react-scripts. Merging this PR as is will break the development server, build process, and test suite. I've added specific comments highlighting the breaking changes. It is highly recommended to either reject this PR or to carefully upgrade dependencies one by one, addressing the breaking changes at each step.

[gemini-code-assist]

The dependency upgrades in this block introduce critical breaking changes:

• eslint (v4 to v9): This major upgrade is incompatible with both eslint-config-react-app (which has a peer dependency on eslint@^4.1.1) and eslint-loader used in this project. This will cause the build to fail.
• css-loader (v0.28 to v1.0.0): This is also a major version upgrade that carries a high risk of breaking changes for this older version of react-scripts.

These automated upgrades are not safe to merge without significant manual migration work.

[gemini-code-assist]

The dependency upgrades in this block introduce several critical breaking changes:

• jest (v22 to v24): The setupTestFrameworkScriptFile option used in your Jest configuration was removed in Jest v24, which will break your test suite.
• postcss-loader (v2 to v4): The webpack configuration for this loader is no longer valid in v4 due to changes in option structure (e.g., removal of ident).
• svgr (v1 to v2): The webpack integration method has changed, and the current configuration may no longer work.

Applying these major version bumps without manual code changes will break the project's test and build processes.
