Steps to reproduce
$c = Import-MarkdownCommandHelp -Path .\Resolve-DnsName.md

$c | export-yamlCommandHelp -OutputFolder . -Force

Import-YamlCommandHelp: Object reference not set to an instance of an object.
Expected behavior
The value `NULL` needs to be wrapped in quotes `"NULL"` when converted to YAML.Actual behavior
The value is being written without quotes so YAML treats it as the YAML null, not the string "NULL".Error details
