Add possibility to load config file from cjs file

[gigaga]

[closes #6911]

Purpose

The newest NodeJS version requires indicating modules loading framework to use (CommonJS or ESM) by using extension file. .js extension is now for using ESM and .cjs for CommonJS.
Currently, from newest NodeJS, it is not possible to use CommonJS framework for TestCafe global configuration file (.testcaferc.js), because this file has to be named .testcaferc.cjs

Approach

This PR allows loading .testcaferc.cjs as TestCafe global configuration file.

@miherlosev

I fixed lint errors ;)

[Aleksey28]

Please fix server tests.

Please fix server tests.

It's done. However, It is not possible to ensure that the whole of tests is ok because it seems not possible to be executed on local env. Isn't it?

It's possible. I see a lot of excessive formatting changes in the current version of the commit. Please roll back these changes.

Hi,

I fixed again lint issues... :(
I disabled my prettier plugin ;)

[Aleksey28]

You still have a few ESLint errors. Please fix them.

At present, there is an issue with building a docker image. We will update this thread once it is fixed.

[gigaga]

The last issue is due to an invalid content in Docker image. Indeed, the content of const Extensions = require('../../lib/configuration/formats'); corresponds to the old value (came from original Docker image FROM testcafe/testcafe:$tag ?):

{
  JS_CONFIGURATION_EXTENSION: '.js',
  JSON_CONFIGURATION_EXTENSION: '.json',
  CONFIGURATION_EXTENSIONS: [ '.js', '.json' ]
}

And expected should be

{
  "js": ".js",
  "json": ".json",
  "cjs": ".cjs"
} 

So, the configurations made with createJsTestCafeConfigurationFile or createJSONTestCafeConfigurationFile are invalid because path is undefined.

I don't know how to fix it...

[miherlosev]

Rebase please.

[gigaga]

Hi @miherlosev

• Before rebasing, I had some tests failed as describing before (old content of Docker image of test/docker/Dockerfile)

• After rebasing, the build of Docker image test/docker/Dockerfile is failed due to Error: ENOENT: no such file or directory, open './package.json'. I executed npx gulp docker-server-test-run --steps-as-tasks

I see that all tests are green. I will ask our technical writers to update the documentation. As soon as it is ready, I will merge this PR.
