fix: disabled org not shown in log

[VincentVerweij]

I have a disabled organization in the organisations.json file:

{
    "organisations": [
      {
        "enabled": false,
        "url": "https://dev.azure.com/my-first-org",
        "pat": "<my-first-org-pat>",
        "processMatch": []
      },
      {
        "enabled": true,
        "url": "https://dev.azure.com/my-second-org",
        "pat": "<my-second-org-pat>",
        "processMatch": []
      }
    ]
  }

I noticed that when executing for example Generate-ProjectStats.ps1 that the logging was showing Skipping and I was wondering what it was skipping.
So, I went looking and found that it is shown for a disabled organization.

This PR fixes the variable used to show the Skipping part.
For Generate-ProjectStats.ps1 it was (notice the emptiness after Skipping):

And after the fix, it becomes (an organisation URL is shown after Skipping):

I only executed Generate-ProjectStats.ps1 but some other files had this small issue as well.
