Allow configuring karma with TypeScript: karma.conf.ts

Allowing the developer to configure karma and be able to type check

Describe the solution you'd like

In the file lib/services/test-execution-service.ts the value for karma config is hardcoded on the line 326. Is it possible to discover the config file in the order similar to the one on the karma website: https://karma-runner.github.io/3.0/config/configuration-file.html ?

Describe alternatives you've considered

Additional context

Here is the location of the code discovering test file in the karma: https://github.com/karma-runner/karma/blob/master/lib/cli.js#L114..L129

閱讀 lib/services/test-execution-service.ts 第 326 行附近的程式碼，並將其中硬編碼的 Karma 設定選擇與 lib/cli.js 第 114-129 行中的 Karma 探索邏輯進行比較。當 CLI 可以探索並使用 karma.conf.ts 設定，讓開發者能夠對其 Karma 設定進行型別檢查時，即視為完成。
