fix: allow bigint in typings

[ViliamKopecky]

ReactNode from @types/react now includes bigint (and its 0n zero which is falsy) and that is incompatible with clsx in these scenarios:

declare const x: ReactNode

const className = clsx(x && 'some-class')
// Argument of type 'false | "" | 0 | 0n | "some-class" | null | undefined' is not assignable to parameter of type 'ClassValue'.
//  Type '0n' is not assignable to type 'ClassValue'.
