bug: The changelog writer interchanging the repo name and org name

[Ramesh7]

Issue

We have observed that the changelog writer generating the link interchanging the repo name and repo org which causing the link to get incorrect while creating Tag. Example : https://github.com/puppetlabs/puppetlabs-peadm/releases/tag/v3.15.0

If you check the above link which has the repo name and org name interchanged which causing the link to be invalid. The generated link : https://github.com/puppetlabs-peadm/puppetlabs/tree/v3.15.0

Expected behaviour

The changelog generator should generate the valid URL. The link should be : https://github.com/puppetlabs/puppetlabs-peadm/tree/v3.15.0
