Rollup 4 support

[lllopo]

Clear and concise description of the problem

@intlify/unplugin-vue-i18n has rollup as dependency, but supports up to Rollup 3 and has no support for Rollup 4. Rollup is already on 4.6, so support for Rollup 4 is not only needed, but the way it goes - soon we will probably need support for Rollup 5 :-).

Suggested solution

Make @intlify/unplugin-vue-i18n compatible with the latest Rollup.
