Fallback to ssh if git https doesn't work

[FabianKramm]

Currently you can only define a git dependency either via https:// or git@ (ssh). Would be great if DevSpace would fallback to try https in the ssh case and ssh in the https case.

So the logic would be for https:

• Try https://domain.com/path, if that doesn't work, use git@domain:path

For ssh the logic would be the reverse
