GetComponentsParams ProviderType field should be Type instead.

[GitH3ll]

Describe the bug
GetComponentsParams struct that is used to populate the GET /components query has a Provider field, which doesn't allow to actually filter components by a specific type. Keycloak API defines type field to filter components by type.

To Reproduce
Steps to reproduce the behavior:
Use Gocloak.GetComponentsWithParams and set ProviderType field to a specific value. Make the request and see that components are not being filtered by their type.

Expected behavior
type query param is used in the request and components are filtered.
