Add high-contrast foreground override for blocked icon

webviews/​editorWebview/​index.css:795

In high-contrast themes, pullRequests.closed defaults to editor.background (package.json:3904-3909). Because non-current readiness badges also use editor.background, this new blocked icon becomes invisible. Please give blocked the same high-contrast foreground override already applied to merged and draft states.
