Write Test in JavaScript

[threeal]

This pull request introduces the following changes for migrating test to use JavaScript:

• Map imported module in the test files to use distribution files.
• Modify the test command to run tsc before testing.
• Remove ts-jest and other related packages from the dependency.
• Convert test files to JavaScript files.
• Remove testMatch option from the Jest configuration file.
• Remove tsconfig.eslint.json in favor of using just tsconfig.json.
• Remove test files exclusion in the tsconfig.json because the test files no longer in TypeScript.
• Modify workflow so that the --experimental-vm-modules node options only be set on Test Package step.

It closes #107.
