The change itself looks fine. I was thinking about representing the code block for the config as a Code Group to better differentiate between npm and pnpm packages.
BUT, this documentation only represents a migration option for ts-jest. By default Jest uses babel-jest. Also, the transformer configuration itself is not that important - only that you have one defined for *.js files. That's why I would probably replace the "transform" section in a more generic way, like this:

// Transform both `ts` and `js` files. Defining only `ts` would not be enough, as we also need to transform @faker-js
transform: {
 '^.+\\.(t|j)s$': 'ts-jest', // use the transformer and configuration of your choice
}
// Exclude from transformation all files in `node_modules`, except `@faker-js`
transformIgnorePatterns: [
 // npm
 'node_modules/(?!@faker-js).+',
 // pnpm
 'node_modules/.pnpm/.+/node_modules/(?!@faker-js).+'
],
