[skara] RFR: bot: don't run watchdogTrigger test on Windows

[Erik Helin]

Hi all,

please review this small patch that disables the `BotRunnerTests.watchdogTrigger` on Windows. The bots aren't fully supported on Windows and this test has a tendency to fail intermittently in our GitHub Actions on Windows. So, lets disable the test on Windows for now until the bots one day might get proper Windows support.

Thanks,
Erik
