Appender test failing on MacOS Sequoia due to new OS behaviour

The hostname check here fails because of what seems to be a bug(?) in MacOS Sequoia that replaces the value for HostName to be the local computer's MAC address.

A workaround is:

sudo scutil --set HostName "your-preferred-hostname"

Hey @angusryer, thanks for your report, much appreciated! Pretty strange what MacOS Sequoia is doing here and you've already provided a workaround. Now, the question is should we fix it in the test suite? It's an easy fix to allow the colons in MAC addresses as hostnames (just prohibit spaces, which I think are actually illegal), so I put out the PR: https://github.com/mschilli/log4perl/pull/135
