Update peerDependency of i18next

[Laberbear]

Currently doing some Angular updates in our application and updated angular-i18next.

Seems like the specified peerDependency of i18next is not valid anymore.
We were using "i18next": "^11.6.0", and ran into build errors from angular-i18next.
Updating to the latest (19.4.3) fixed this.

@Laberbear Hmm.. strange, whats angular version are you using?

I use 9.1.3, have the same problem after and before updated i18next

Updated demo (angular: 9.1.6, i18next: 19.4.4). It works without problem.

i18next in most cases is safe to update, please use latest version, if you have problems.

I'm going to raise up i18next dep in future version (as soon as angular 10 comes out): #52
