Implement a proxy to hit the Artifacthub.io API end point

Description

Hitting the Artifacthub.io search endpoint fails sometimes due to a CORS error and the Version API endpoint always fails due to a CORS error. So, we need a Proxy to hit the Artifacthub. end point to get the data.

Acceptance Criteria

1. Create a proxy to hit the Artifacthub.io endpoint.

Additional Details:

Search endpoint: https://artifacthub.io/docs/api/#/Packages/searchPackages

eg.: https://artifacthub.io/api/v1/packages/search?offset=0&limit=20&facets=false&ts_query_web=git&kind=7&deprecated=false&sort=relevance

Version endpoint: https://artifacthub.io/docs/api/#/Packages/getTektonTaskVersionDetails

eg: https://artifacthub.io/api/v1/packages/tekton-task/tekton-catalog-tasks/git-clone/0.9.0
