Update-PSModuleManifest -FunctionsToExport breaks PSAvoidTrailingWhitespace scriptanalyzer rule

[JensGJ]

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.

Steps to reproduce

I use a build script to generate powershell modules. The tasks of the build script include updating the module manifest to list the FunctionsToExport - and a call to Invoke-ScriptAnalyzer to ensure that the code follows best practice.
The problem is that Update-PSModuleManifest -FunctionsToExport splits the array across multiple lines in the psd1 file in a way that violates the PSAvoidTrailingWhitespace rule from Invoke-Scriptanalyzer.

I discovered the behaviour in Update-ModuleManifest from PowerShellGet but I have verified that the newer Update-PSModuleManifest has the exact same behaviour

Steps to reproduce:
New-ModuleManifest -Path foo.psd1
Update-ModuleManifest -Path foo.psd1 -FunctionsToExport "Get-Something", "Convert-SomethingElse", "Add-MyFunction", "Remove-TheLineBreak"
Invoke-ScriptAnalyzer .\foo.psd1

Expected behavior

(no output)
