The buildpack build strategy instructions has a misleading note on the limitations of the shp CLI. It is true that developers must provide a unique name to the `shp buildrun create` command. However the CLI has an alternative command that does this on behalf of developers - `shp build run` - that is easier to use and should be preferred in the documentation. The buildah and s2i build strategies use this command instead.

The buildpacks instructions should be updated to be consistent with the other build strategies.
