fix s-34 solution screaming Argument of type '[]' is not assignable

[nthhai318]

Description

Solution 34 - 34-internationalization.solution line 38: Typescript is screaming

  const buttonText = translate(translations, "button");
// Argument of type '[]' is not assignable to parameter of type 'never'.
// Translation: I was expecting never, but you passed []

  ...args: TDynamicKeys extends string
    ? [dynamicArgs: Record<TDynamicKeys, string>]
    : []

Because TDynamicKeys (line 15) become never in case of button property of transalations
causing ...args to become type never

Fixes

check if TDynamicKeys is type never first

  ...args: [TDynamicKeys] extends [never] 
    ? []
    : TDynamicKeys extends string
    ? [dynamicArgs: Record<TDynamicKeys, string>]
    : []
