Extension overwrites native colors of the theme

Issue Description

So I updated to the newest version thinking it would solve the issue with theme colors being all green, and partially it did. But only partially. It's still green, just a bit less of it

This is native theme:

I get that there may be a difference between how theme highlights colors and how extension highlight colors but it should use theme colors, not just overwrite with predefined color set.

And to be honest it seems highlighting is better in theme, then by extension (ValueFromPipeline/Mandatory) gets additional highlighting. Same for $null.

PowerShell Information

Visual Studio Code Extensions

Beginne damit, das Farbverhalten in Visual Studio Code mit der PowerShell-Erweiterung und dem im Issue beschriebenen Theme zu reproduzieren. Lies die Hinweise zur Fehlerbehebung in docs/troubleshooting.md, falls Logs benötigt werden. Als erledigt gilt die Aufgabe, wenn die nativen Theme-Farben erhalten bleiben und die PowerShell-spezifische Hervorhebung, einschließlich Parameterattributen und $null, weiterhin funktioniert.
