Add support Vue 2|3, refactoring code

[rah-emil]

I don't think it's worth keeping the old syntax with filters. Even the Vue developers don't recommend doing this either.

I propose a solution that contains support for two versions of Vue, which also passes all the tests you wrote (only, I changed the main moment prototype, it now does not contain the $ symbol).

I also updated the README

I need this plugin for a project on Vue 3, and there is no time to wait for the merge. I posted my version to myself, but made a revert of these changes for merging with you.😇

I think this all makes sense to me, great work 👍 I think it would be wise to give this package a major package bump when we merge this in, to cover for the breaking changes.

Thank you! Write what you need, I'm ready. I would love to be on the list of collaborators)
