fix(webhooks): support image names containing a port number (#4526) (#5970) 

This fixes a bug where image/registry names that contain a port number were inadvertently truncated (because port numbers are specified with a colon, just like the image tag).

For example, updating an image named `registry.example.com:5000/myimage:oldtag` with the new image tag `newtag` was incorrectly transformed into `registry.example.com:newtag`
