Rename module name and imports

[marctc]

I tried to import the exporter using the new organization but I got this error:

        github.com/githubexporter/github-exporter/config: github.com/githubexporter/[email protected]: parsing go.mod:
        module declares its path as: github.com/infinityworks/github-exporter
                but was required as: github.com/githubexporter/github-exporter

I suspect is because the module name was not renamed. This PR changes it.
