deps: Update piscina dependency to v4.3.1.

[garg3133]

Updating Piscina dependency to the latest version (v4.3.1) partially solves issue #4009 in that the main process no longer exits completely without showing any error in case of uncaughtException or unhandledRejection in one of the worker threads. Instead, any such error in worker threads is handled properly now, thanks to piscinajs/piscina#361, and the error message appears in the console output of the affected test suites.

But there are still two issues remaining to be resolved for such cases:

• In case of an unhandledRejection or uncaughtException, the browser session is not closed properly and the browser window remains open while the test run exits. This happens in both serial and parallel mode of execution.
• While the process does not exit now in case of error in a worker thread and the error appears in the console output, the final report does not show any error, which might lead to errors in such cases getting missed out.
