### Link to the code that reproduces this issue or a replay of the bug

https://github.com/BlackPoretsky/testplane-error-ts

### Reproduction steps

1. Set in `package.json` `"type": "module"`
2. Set the extension of the configuration file to `.ts`
3. Start the `npx testplane`

### Actual Behavior

The error:
`[ERR_REQUIRE_ESM] is selected: import must be used to load the ES module:
E:\WEB_LEARN\testplane-error-ts\testplane-error-ts\testplane.config.ts The require() function for ES modules is not supported.
require() of E:\WEB_LEARN\testplane-error-ts\testplane-error-ts\testplane.config.ts from E:\WEB_LEARN\testplane-error-ts\testplane-error-ts\node_modules\.pnpm\testplane@8.25.4_@types+node@22.13.14_ts-node@10.9.2_typescript@5.7.3\node_modules\testplane\build\src\config\index.The js is an ES module file, since it is a TS file, the closest parent package file.the json of which contains "type": "module", which defines all ts files in the scope of this package as ES modules.
Instead, change the required code using the import() function or remove "type": "module" from E:\WEB_LEARN\testplane-error-ts\testplane-error-ts\package.json .`

If you change the configuration file extension to `.cts`, the tests run, but test files with the extension `.ts` are not accepted and an error is returned: `TypeError: Unknown file extension ".ts" for E:\WEB_LEARN\testplane-error-ts\testplane-error-ts\testplane-tests\example.testplane.ts

The `system.fileExtensions` field in the configuration has not changed.
And if you replace the extension for test files with `.js` then the tests run successfully, but I would still like to use `.ts`.

### Expected Behavior

The tests should have been run.

### Which Node.js version are you using?
