Code Review

This pull request, automatically generated by Snyk, updates gatsby and gatsby-transformer-remark to fix several security vulnerabilities. However, the update for gatsby is a major version jump from v2 to v5, which introduces significant breaking changes. The project is likely to be in a broken state if this PR is merged as-is, due to incompatible Node.js and React versions, as well as outdated Gatsby plugins. I've left a critical comment outlining the necessary additional changes to ensure a successful migration.

[gemini-code-assist]

This major upgrade of Gatsby from v2 to v5 introduces significant breaking changes that will likely break the build. While this upgrade fixes security vulnerabilities, it requires several other changes to make the project compatible.

Here are some of the required changes:

• Node.js Version: Gatsby v5 requires Node.js v18 or newer. The root package.json specifies "node": ">=6.11.5", which is incompatible. The engines field in the root package.json needs to be updated.
• React Version: Gatsby v5 requires React v18. This package.json specifies "react": "^16.4.0" and "react-dom": "^16.4.0". These must be upgraded to ^18.0.0.
• Gatsby Plugins: Other Gatsby plugins in this project are likely incompatible with Gatsby v5. For example, gatsby-source-filesystem is at version ^2.0.1. All gatsby-* plugins should be audited and upgraded to versions compatible with Gatsby v5.
• Monorepo Consistency: Other packages in this monorepo, such as the one in the www directory, also use Gatsby v2. A full migration across the repository might be necessary for consistency and to avoid build issues if these packages have inter-dependencies.

Simply merging this PR will likely lead to a broken state for the styleguide example. A more comprehensive upgrade of all related dependencies is needed.
