As mentioned in PowershellFrameworkCollective/psframework#645 (comment) , after updating to 2.2.12.171 of PSModuleDevelopment, the Invoke-PSMDTemplate command started generating files where part of the content is missing.

See Test Invoke-PSMDTemplate for a comparison. Both of the following files were generated with the following command:
Invoke-PSMDTemplate CommandTest -Name Invoke-PSMDTemplate

• Invoke-PSMDTTemplate.Tests.2.2.11.168.ps1 was generated with the previous version 2.2.11.168 of PSModuleDevelopment (as well as the older version 1.11.343 of PSFramework)
• Invoke-PSMDTTemplate.Tests.2.2.12.171.ps1 was generated with the current version 2.2.12.171 of PSModuleDevelopment

The issue occurs on Windows Server 2022 with Windows PowerShell 5.1.
