comark/code/unknown-frame · Set frame to "terminal", "code", or "none"

comark-code draws a block as a terminal, as a code editor, or with no frame. Any other frame, such as window, is left out, and the block falls back to the frame its language gives it.

Incorrect

```sh frame="window"
pnpm run deploy
```
