Validate links of private github repositories

[volker-raschek]

I've running the markdown-link-checker as container image in my CI. The README.md contains some links to a private GitHub repository and throws an 404 status code, because the application tries to access unauthorized the git repository.

How can be defined a PAT to make an access possible? Alternatively, is a .netrc file supported?
