Docs/ ReadMe needs more transparency

Describe the bug
While using the package, I noticed that it appears to be compatible only with Vue 2, as discussed in issues #123 and #64. However, this information is not clearly stated in the ReadMe.

I propose updating the ReadMe to explicitly mention that the package is designed for Vue 2. This will help users quickly understand the compatibility and save time for developers exploring Vue 3 or Nuxt 3 compatibility.

Package Version
1.8.0

https://github.com/raiblaze/vue3-html2pdf as per the readme in this (vue-html2pdf) package, this supports vue3 as well. I am still not sure how to make it work with vue3 though.

@kempsteven can you please confirm this?
