Version v2021.2.2 doesn't highlight the #Requires statements

Environment

• Editor and Version (VS Code, Atom, Sublime): VSCode 1.53.2
• Your primary theme: Dark+ (default dark)

Issue Description

I just opened some PowerShell scripts and the extension got updated. Right in front of my eyes, I had some #requires statements and they got their highlight stripped off.

Screenshots

Expected Behavior

The only Theme which still highlights those statements that I found is Night Owl. I have like 10 themes installed and went through all of them and the Night Owl is the only one.
