fix: workbench search use correct findMatch colors (fix #237909)

[simon-id]

Motivation

Fixes: #237909

With this user configuration, find match text color are improperly rendered when using Workbench Search (not the widget search):

    "workbench.colorCustomizations": {
        "editor.findMatchHighlightForeground": "#000000",
        "editor.findMatchHighlightBackground": "#ffffb4",
        "editor.findMatchForeground": "#000000",
        "editor.findMatchBackground": "#ff4cde"
    },

Before fix:

After fix:

Code changes

Add the inlineClassName field to the Workbench Search ModelDecorationOptions to properly render the editor.findMatchForeground and editor.findMatchHighlightForeground colors.

This field is copied directly from the ModelDecorationOptions in src/vs/editor/contrib/find/browser/findDecorations.ts, as the widget search properly renders the foreground colors.
