Played variant for daily challenge counter

[cl8n]

see the design file. this is a small update adding a variant of the daily challenge streak for when the user has completed today's challenge, already approved by flyte and myself

also, the corner radius of that darker block is supposed to be 3px, it's 6px on osu-web rn for some reason.

I wasn't sure whether to just post it here or open a discussion at https://github.com/ppy/osu-design, the latter felt kind of overkill for such a tiny thing but maybe I'm overthinking it, I'm not sure. we're still figuring this out lol

this is a response to https://discord.com/channels/188630481301012481/1097318920991559880/1300323179457151069

I'll do the client change for this after the web pull has gone through review paces, since I'm not 100% on the web pull to begin with.
