Please update document for avalonia 11

[butaixianran]

From avalonia 11, ViewLocator is removed from project template, which is needed by this package but not mentioned in document.

So people need to know, they have to create their own ViewLocator class.

Also, to use this package, we need to install package Microsoft.Extensions.DependencyInjection, which is also not mentioned in document.

Oh, this is interesting. Thanks for bringing this up.

This is a dependency that only provides a small amount of convenience and will be removed in the next release. But thanks for pointing this out :-)

Should now be fixed - 0.0.4 release is going online automatically in a few hours. Feedback welcome, feel free to reopen, if there is anything wrong with it :-) Thanks again for bringing this up.
