Add Missing Methods for Workflow/Notification group

[mr-palindrome]

Some endpoints of the workflow groups can't be hit from this SDK.

As https://api.novu.co/api#/Workflow%20groups contains several API endpoints for listing and doing CRUD operations on the workflow groups (under notification group in the source code). Some of these missing methods are as follows:

• [x] get (method to get a single group)
• [x] patch (method to update a single group)
• [x] delete (method to delete an existing group)

For reference:

• https://docs.novu.co/api-reference/workflow-groups/get-workflow-group
• https://api.novu.co/api#/Workflow%20groups
