Fix display of wordle stats histogram on moblile

[h-anjru]

Ain't much to it.

• Shortened max length of string by one character for better display on mobile. (Embed formatting must have changed somewhere along the way, necessitating this change.)
• Gave more room to the histogram itself by shortening labels "quit" and "10+" to "Q" and "+" respectively.
