fix: use correct Git Server URL and auth details for lighthouse as for scm provider

[cameronbraid]

This fixes it for me when using gitea, not sure if this is the proper way to fix it. It just re-uses the same git url and auth details as the scm provider uses

fixes #424

Hi @cameronbraid. Thanks for your PR.

I'm waiting for a jenkins-x-plugins or todo member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Linting fails:

pkg/cmd/start/start.go:451:17: Error return value of `o.FindGitToken` is not checked (errcheck)

Run locally make lint with golang-ci lint 1.42.1 (the latest - 1.45.X will give much more errors, we will update it soon)
