useTrackEvent typing improvement

[nandi95]

Describe the feature

useTrackEvent doesn't have the same typing as the useGtag()('event', ....nicely typed args)

I tried to implement this but didn't get far with it. Not easy when I only have the GTag type to work with.

import type { Gtag } from '../types'
import { useGtag } from './useGtag'

type Event = Gtag | ((command: 'event') => never)
type OmitCommandParameter<T> = T extends (command: 'event', ...rest: infer R) => void ? (...args: R) => void : never

export function useTrackEvent(
  eventName: Parameters<OmitCommandParameter<Event>>[0],
  eventParams?: Parameters<OmitCommandParameter<Event>>[1],
) {
  const { gtag } = useGtag()
  gtag('event', eventName, eventParams)
}

Perhaps other types can be exported too?
It would make sense in case someone constructs the arguments outside of a function call.
