chore: fix jest esm tests

[rostyk-kanafotskyy]

What/Why/How?

This update to the jest.config.ts and the addition of setup-jest.js includes several modifications, focusing on enabling ESM (ECMAScript Module) support for Jest and updating how configurations are applied. Here’s a summary of the key changes:

• ESM Configuration in ts-jest:
  • The useESM: true setting was placed within globals.ts-jest which is now deprecated.
• A new setup file, setup-jest.js, is created to handle ESM-related setup for Jest. It imports jest from @jest/globals and assigns it to global.jest, making Jest functions available globally in the ESM environment.
• Additional Config Changes:
  • setupFiles in jest.config.ts now includes setup-jest.js, ensuring it runs before tests to properly set up Jest in the ESM environment.

These changes should help in achieving a smooth transition to ESM, particularly with module compatibility in Jest.
