Issue: [less] support `each` in keyframes
Labels: bug,css-less-scss

Type: <b>Bug</b>

la sitassi .less (css pre processor)

```
@keyframes passataBlu {
   each(range(0,10), { //*** Non è un errore è la parentesi giusto così!!
      @{value}0% {
       background-image: linear-gradient(90deg, transparent 0%, blue (@value*10-10%), transparent 100%);
       -webkit-background-clip: text;
     }
   })
}
```

E' corretta e funziona bene in chrome, ma VS Code da errore sulla parentesi tra **each** e **range**.

Ma il codice è in realtà corretto! funziona da less 3.9.0 in su!

Si può togliere questa falsa segnalazione?
Grazie
