Add entire.io extra

[yarikoptic]

as I am exploring it and @candleindark prepping example for STAMPED

FTR my invocation

./setup-yolo.sh --build=yes --packages="ffmpeg,imagemagick,yt-dlp,nodejs,podman,podman-compose,curl,tmux,ncdu,pre-commit,latex-make,xterm,xdotool,psmisc,cowsay" --extras=playwright,entire,deno

locally ATM

Now that I have an escape plan if the dockerfile becomes unwieldy I'm not concerned with bloat.

FWIW I think this does highlight an improvement in my WIP way, which is that extras can take arguments ie, version.

Another small concern is that the go version is pinned by the extra. Might hit trouble if we add other go tools.

But since individual extras dont accept args I think let's just merge, and if we hit these issues we can fix then.

yeah, I actually also thought to fix it by version, would be prudent... let's do that...

Could you also add this to the spec?
