Model->getMetadata TypeError

[timbit123]

Hello
I have an error with the function, it can return an array not only a string
For exemple if you call it with ->getMetadata('labels')

"Return value of Maclof\Kubernetes\Models\Model::getMetadata() must be of the type string or null, array returned"

kubernetes-client/src/Models/Model.php

Line 82 in b726e64

public function getMetadata(string $key): ?string

Thank you

This should be fixed after merging #118

For now this can be used instead

->toArray()['metadata']['labels']
