Refactor test scripts for improved reliability and clarity

- Updated `run-robot-tests.sh` to enhance the verification of the Deepgram batch worker process, ensuring non-numeric characters are removed from the check.
- Modified `plugin_tests.robot` to use a more explicit method for checking the length of subscriptions and added a skip condition for unavailable audio files.
- Adjusted `plugin_event_tests.robot` to load the test audio file from a variable, improving test data management.
- Refactored `plugin_keywords.robot` to utilize clearer length checks for subscriptions and event parts, enhancing readability and maintainability.
