Update repo name

[meeech]

Hey @wilsonwu & @izturn

Just wanted to make you aware of argoproj/argo-rollouts#2720

We are updating the naming convention for plugins for rollouts.

So in your case, the repo would need to move to rollouts-plugin-trafficrouter-contour

I hope this isn't too much of an inconvenience.

Thanks for this notice, no problem for this change.

And I have updated it, any problem please let me know.

Both repo name and package updated.
