Fixes #18126

I've done quite a bit of experimenting with the test on mono on linux:
The test itself always finishes fine, but the mono binary gets stuck on shutdown. I attached gdb and didn't see anything suspicious and it seemed that all the managed threads have finished. My theory is that the binary fails to exit because of this:

• mono runtime keeps track of "managed" and "native" threads and the main thread won't exit until all the managed threads have finished.
• when a managed callback is invoked on an otherwise "native" thread (this happens when the log handler callback runs), mono promotes the native thread to a "managed" thread.
• when the test's Main returns, some of the native threads (e.g. timer thread) that usually don't prevent the process from exiting have been promoted to "managed" and they keep the process alive. (forever, which eventually leads to the test timeout).

The workaround is to disable the logging/tracing part of the test on Linux and Mac, because we are interested in testing on Windows only anyway (where the test passes reliably, according to the test result history)

The PR also fixes a few typos.
