tc function is missing in typescript definition (in Composer interface)

Reporting a bug?

Typescript gives an error Property 'tc' does not exist on type Composer<...> in the code like that:

import { useI18n } from 'vue-i18n'
const i18n = useI18n()
const a = i18n.t('something') // <- this one is ok
const b = i18n.tc('otherthing', 1) // <- this one gives typescript error

It's indeed missing in vue-i18n.d.ts Composer definition (the first 500 rows). However it exists in the VueI18n interface.

I have to use it like

import { useI18n, VueI18n } from 'vue-i18n'
const i18n = useI18n() as unknown as VueI18n

to get rid of this error, which is not nice.

Expected behavior

tc function should just work without any typescript error
