fix(random): describe /gachabeta generically and match its new length

The beta renderer changed style, so /gachabeta now reads "Gacha (beta
version)" in its command description, package doc, README row, and deploy
guide instead of naming one look. The clip length sent to Telegram is 11
seconds to match the renderer's 10.5-second beta animation.
