Implement Vue 2 support for v2.

[gkweb]

Vue 2 support is still possible with some very very minor changes.

Are you open to supporting both?

I'd be happy to open a PR. This might see the folder structure change slightly to support both versions of Vue gracefully.

Hi @gkweb,

Support for Vue 2 was not envisaged in v2, and frankly, I don't see a way to support both Vues in the current environment. If you do, I'd be happy to check out your PR.

@hrynko - Rough proposal before I spend any time there. See detail and let me know your thoughts?

Workspaces set up in the repo

Vue 2 in workspace will sit in @vue-pdf-embed/vue2

And consumed when published to npm via vue-pdf-embed/vue2/* Vue 3 is consumed as normal under: vue-pdf-embed/*

proposed folder change:

• packages/
  • core
  • @vue-pdf-embed/core
  • current project and associated ts / .vue
  • The ONLY minor change to the vue implementation is to switch out toValue to unref
  • Types - Look at adding a checked inMaybeRef (doesn't exist for vue 2).
  • vue2
  • @vue-pdf-embed/vue2
  • package.json
    • Will hold different Vue deps (vue 2) and vite build deps
    • will build output into packages/vue2/dist OR workspace root /dist/vue2 TBC

Friendly bump of that proposal @hrynko - thoughts?
