fix(3415): Do not treat "internal" repo as "private"

[sagar1312]

Context

Internal repositories are being marked and treated as private repositories.

The current logic in GitHub SCM module only relies on private property from the GitHub API response to identify whether a repository is private or not.
But, this property alone is not sufficient. Both private and internal repositories will have private: true.

Objective

In addition to private property, we also need to check the value of visibility property.

Repository Type	API Property: private (Boolean)	API Property: visibility (String)	Description
Public	false	public	Accessible to everyone on the internet.
Private	true	private	Only accessible to the owner and explicitly shared collaborators/teams.
Internal	true	internal	Accessible to all members of the organization/enterprise, but hidden from outsiders.

Mark the repo as private when all the below criteria are met

• "private": true
• "visibility": "private"
