[u-boot-test-hooks PATCH] Update Contributing.md with up-to-date information

[Bin Meng]

As Stephen is no longer actively maintaining the uboot-test-hooks,
and the repo itself has been moved to source.denx.de, update the
Contributing.md with up-to-date information on how patches should
be sent against this repo.
