Feature Description

Luxon just released the version 2 of the library. Some people realized this and created a feature request ticket

According to the upgrade from 1x to 2x guide we would need to update:

• .fromObject
  • https://github.com/fullcalendar/fullcalendar/blob/master/packages/luxon/src/main.ts#L24
  • https://github.com/fullcalendar/fullcalendar/blob/master/packages/luxon/src/main.ts#L91
• OS timezone is called system instead local but local still works

While the change itself is easy I think it is hard to manage the versioning because this requires the luxon peer dependency to be upgraded to V2.

I see several options:

1. Update luxon peer dependency to ^2.1.0 and release a new version of fullcalendar with this breaking change.
2. Create a new package luxon-plugin-v2 with this changeset so we don’t need to release a major fullcalendar version.

I’ve already got a fork and I’m happy to help with those changes but I would like the contributors opinion first. Thx for this amazing project 🚀

I have just released a new plugin that will solve this problem: https://www.npmjs.com/package/@fullcalendar/luxon2

I plan on documenting this today. However, there’s not much to document. Simply use this if you want Luxon 2 support.
