PowerShell comment syntax highlight is not correct.

We have written the needed data into your clipboa
Issue Type: Bug

The highlight syntax for comments is wrong for PowerShell files.
EG.

.\procedure.ps1 `
   -arg1 $variableforarg1 ` #this syntax highlighting should not resemble a comment
   -arg2 $variableforarg2 ` <#this syntax highlight should not resemble a comment because it's invalid to add a comment here #>
   -arg3 $variableforarg3 <#this syntax higlight should be correct#>`
   -arg4 $variableforarg4

The example above shows that the "arg1" and "arg2" have incorrect comments and should not by syntax higlighted as comments.

For me saddly as a beginner powershell user this was an issue when trying to deploy :(. Just want to make that you have a visual cues when using this and not commit a faulty powershell script in production like me.
P.S. if you use the PowerShell ISE it will syntax highlight correctly.

@stefanita-mitran I can reproduce this, but it also occurs in PowerShell ISE. I'll move this issue to the owners of the PowerShell grammar.
