In dark mode, 'white' is black

[terryjreedy]

"White packages have no wheel archives uploaded (yet!)." In my up-to-date Firefox browser, pythonwheels displays in my preferred dark mode and pyspark, is white on black versus white on green. Either add a note in the text, or explicitly set a white background in the column the same way you set green backgrounds. I would prefer the latter. (I checked for existing issues, did not find.)
