test(sqllab): fix tsc failure in selected-word marker test

The shared `render` helper from `@superset-ui/core/spec` omits `wrapper`
from its options (it always supplies its own SupersetThemeProvider), so
passing a custom `wrapper` tripped TS2353 and failed the lint-frontend
tsc step. Nest the dark theme around the editor element instead; the
innermost emotion ThemeProvider is what the editor's useTheme() resolves,
so the assertion still exercises the dark-aware marker color.
