documentation: Change tag template link location for build triggers (PROJQUAY-6044) (quay#2234)

The documentation link on the build trigger tag template screen is currently pointing to the location of the `schema` directly in the code.
This is not really useful or user friendly. This will repoint that documentation link to the KCS article written for this purpose.
