Good pratice to update moduleFileExtensions for jest

[melroy89]

According to the jest documentation, you might want to change the default order of moduleFileExtensions in jest.config.cjs (in your case jest.config.ts).

Read: https://jestjs.io/docs/configuration#modulefileextensions-arraystring

We recommend placing the extensions most commonly used in your project on the left, so if you are using TypeScript,
you may want to consider moving "ts" and/or "tsx" to the beginning of the array.
