Support For Artifact Hub API

[PuneetPunamiya]

Currently to show the tasks, console uses Hub API's (as default one's) to get all the tasks and information regarding those tasks For example ---> https://api.hub.tekton.dev/v1/resource/tekton/task/git-clone/0.7

Based on the discussion in this issue ---> https://github.com/tektoncd/hub/issues/667#issuecomment-1262783981 Artifact Hub also has API's which has support to list the tasks and get the detailed information about the tasks For e.g. ---> https://artifacthub.io/api/v1/packages/tekton-task/tekton-catalog-tasks/git-clone/0.7.0

Hence, there should be a provision to support Artifact Hub API's
