Documentation - Update @kazupon/vue-i18n-loader to @intlify/vue-i18n-loader

[fbigand]

When installing vue-i18n-loader for my project, following the documentation, I had this message
@kazupon/vue-i18n-loader@0.5.0: WARNING: If you would like to use @kazupon/vue-i18n-loader that is released new features and bug fixes, you need to install @intlify/vue-i18n-loader

After looking at the github project, I found that the command to run is this one npm i --save-dev @intlify/vue-i18n-loader@next.

So I changed the command, and references to @kazupon/vue-i18n-loader with @intlify/vue-i18n-loader

Thank you for your contribution!

Sorry, late my response.

Could you fix the below docs, please? 🙏

Thank you for this indication and sorry for late response.

I updated the pull request with changes on the file in vuepress folder.
I additionally updated the links to the github folder.
Since the html files are generated, I left my original commits, let me know if this need to be reverted.

Also, I am not entirely sure if this needs to be changed, (sfc.md, line 178, Laravel-Mix paragraph).
// The below code will inject i18n Kazupon/vue-18-loader as a loader for .vue files.
