<#
.SYNOPSIS
    Add detailed information about a check so that it can be displayed in the report.

.DESCRIPTION
    This function is used to add detailed information about a test so that it can be displayed in the test results report.

    The description and result support markdown format.

    If the calling script/cmdlet has a markdown file with the same name as the script/cmdlet,
    it will be used to populate the description and result fields.

    The markdown file can include a seperator `<!--- Results --->` to split the description and result sections.
    This allows for the overview and detailed information to be displayed separately in the Test results.

.EXAMPLE
    Add-ZtTestResultDetail -Description 'Description' -Result 'Result'

    This example adds detailed information about a test with a brief description and the result of the test.

    ```powershell
        $policiesWithoutEmergency = $policies | Where-Object { $CheckId -notin $_.conditions.users.excludeUsers -and $CheckId -notin $_.conditions.users.excludeGroups }

        Add-ZtTestResultDetail -GraphObjects $policiesWithoutEmergency -GraphObjectType ConditionalAccess
    ```

    This example shows how to use the Add-ZtTestResultDetail function to add rich markdown content to the test results with deep links to the admin portal.
