There are small problems in the ModuleHelp.Tests.ps1 file when running tests on Pwsh, or running on an environment without PSScriptAnalyzer actually installed.

affected areas:

1. test failure when PSScriptAnalyzer is not installed (only loaded from the .\out\ directory)
2. test failure on Pwsh due to non-supported 'Workspace' command type

Steps to reproduce

1. on a system without PSScriptAnalyzer module installed
2. when build configuration is set to DEBUG

.\PSScriptAnalyzer\build.ps1
.\PSScriptAnalyzer\build.ps1 -Test

Expected behavior

1. No test failures
2. No test failures

Actual behavior

1. Test fails to properly check module version, because it was not installed, only loaded from .\PSScriptAnalyzer\out\
2. Test fails with an error that the 'AttachAndDebug' parameter for Invoke-ScriptAnalyzer and Invoke-Formatter does not have Help.
