Scrollbar styling does not match VS Code theme

[dogusata]

Problem

The styling of the scrollbar, especially the color and the width, don't match the other scrollbars in the VS Code interface.

Steps to reproduce the issue

Install Amazon Q in VS Code.
Switch to any dark theme in VS Code.
Observe Amazon Q's scrollbar is jarringly bright white, wide, and different from the grey and narrow scrollbars in the rest of VS Code's interface.

Expected behavior

Scrollbar styling should follow the IDE not the OS. Since OS can have light theme but the IDE can have a dark one.
