Defining registry access for code scanning default setup

What changes are you suggesting?

The documentation states that https://nuget.pkg.github.com/ should be used as NuGet feed URL for Dependabot.
However, this base URL causes HTTP 405 errors when Dependabot attempts to resolve packages, resulting in partial updates, only projects that don't reference private packages get updated, while others are silently skipped.

When the URL is changed to the org-scoped format https://nuget.pkg.github.com/{org}/index.json, Dependabot resolves packages correctly and all projects are updated as expected.

Should the documentation recommend the org-scoped URL instead?

@loekensgard The URL should probably by changed, but I will check with the Dependabot team to make sure it's not a bug that they need to fix.

@loekensgard Yep, they say the URL needs to be updated! Should be a simple fix, so I'll put a help wanted label on this, and you or anyone else can open a PR to update it.
