docs: fix Warn/Warning key mismatch in guides/logging.md

[HeyItsGilbert]

Summary

The logging guide example uses the key Warning when the correct key (matching the Effect enum and the Configuration.psd1 structure) is Warn. The example line is a silent no-op.

File

guides/logging.md:80

Current (wrong)

$config.Logging.Warning.Enabled = $true

Fix

$config.Logging.Warn.Enabled = $true

If Issue #15 is resolved by renaming the config key to match Warning, this guide should use Warning instead.
