Steps to reproduce

Noticed that both VSCode and GitHub doesn't highlight some variables, like $Error and $PSVersionTable

This:

```powershell
#Requires -Version 5.1
$SomeVariable
$Error
$PSVersionTable
string without quotes
'string with quotes'
```

Looks like this on GitHub:

#Requires -Version 5.1
$SomeVariable
$Error
$PSVersionTable
string without quotes
'string with quotes'

And in VSCode:

Expected behavior

Highlight.js demo https://highlightjs.org/demo does as I expect it to:

PowerShell ISE and the PowerShell terminal too:
