chore(playground): compatible with esm-only unocss

description

This PR is to close #321.

After checking, only some repositories under package/playground don't set type: "module". Sub packages such as applet, client, overlay, etc. have worked well with ESM.

I have removed the verbose Unocss dependencies.
I think dependencies need to be listed explicitly, even if it can work with the setting of shamefully-hoist=true in the .npmrc.
