Support for i18next ^22.0.0

[belgattitude]

🚀 Feature Proposal

Support for latest i18next major release https://github.com/i18next/i18next/releases/tag/v22.0.0

Motivation

Benefit from upstream typescript improvements.

Proposal

next-i18next has an explicit dependency on ^21.9.1

The easiest is to update to ^22.0.0.

PR: #1966

That avoids situations where 2 instances would be installed (an currently make it hard to debug)

└─ nextjs-app@workspace:apps/nextjs-app
   ├─ i18next@npm:22.0.0 (via npm:22.0.0)
   └─ next-i18next@npm:12.1.0 [f054d] (via npm:12.1.0 [f054d])
      └─ i18next@npm:21.10.0 (via npm:^21.9.1)

As per i18next changelog there should not be breaking changes between the two versions. So it should be fine

PS: An alternative approach is to move i18next to peerDependencies with a range

  "peerDependencies": {
    "i18next": "^21.9.1 || ^22.0.0"
  }

Installation instructions will need to be updated, ie: yarn install next-i18next i18next... (+ major would clarify the change)

Thanks for the amazing work

will be released in next major
