feat: jest with esm support

[sublimator]

Changes

1. Unified jest.config.cjs: We've simplified our Jest setup by deploying one jest.config.cjs file in each workspace. This file now treats .mts files as ESM by adding them to extensionsToTreatAsEsm and moduleFileExtensions. The configuration now also collects all workspace Jest configurations as projects.

2. Removal of jest-e2e.config.cjs: We've deleted the jest-e2e.config.cjs files, further streamlining the configuration process.

3. Usage of PROJECT_JEST Variable: The PROJECT_JEST environment variable should be set in the package.json scripts in each workspace. This signals to Jest when workspace tests are run directly, rather than being collected from the monorepo root.

4. Update in package.json Test Scripts: In the test scripts of the root package.json, we've set the NODE_OPTIONS variable to --experimental-vm-modules.

5. Removal of @types/jest: We've removed @types/jest and now import globals from @jest/globals instead.

By employing this strategy, we've streamlined the Jest configuration process for ESM support, improved the manageability of Jest setup for each workspace, and facilitated a smoother, more gradual transition from CJS to ESM.
