I suggest about Japanese GUI font-family. (not editor font family)

Current vscode specified "Meiryo" in Japanese font-family, but normally Windows 10 using "Yu Gothic UI" as Japanese system font.
We should add Yu Gothic UI to vscode font-family because Yu Gothic UI has a better character width and rendering than Meiryo.

Current (workbench.main.css)

.windows:lang(ja) {
    font-family: Segoe WPC, Segoe UI, Meiryo, sans-serif
}

Suggestion (workbench.main.css)

.windows:lang(ja) {
    font-family: Segoe WPC, Segoe UI, Yu Gothic UI, Meiryo, sans-serif
}
