fix #283

[ArtrenH]

The method getDomainsdoes not exist on the panel object in newer versions of filament. Therefore, installing breezy throws an error and makes the plugin unusable.
The new method name is getDomain. With this function, the installation process runs smoothly and the library is usable again.

@ArtrenH can you please explain further?
Using Filament v3.2.2 the method I see is still getDomains()

Running my laravel server without the patch, I get this error:

I am on filament version 3.0 though and it seems that this is a me-problem and it seems to be fixed in the latest version:

Are you sure you're on the latest version of Filament? Earlier versions of Filament v3 had getDomains() but it was updated to getDomains().

Either way, Breezy must have a dependency issue if composer is installing incorrect versions. I'll have to look at this, but in the meantime please ensure you're on the latest version of Filament or at least v3.1
