chore: move to kuadrant v1.3 final

This updates install script to setup Kuadrant v1.3 final version.

Additionally, the `installation.md` page has been updated to no longer require `jwt` tool, and to use the right hostname of the MaaS Gateway.

Also, the namespace manifest is removed, because it is pre-created by `deploy-openshift.sh`. This is inline with other ODH components where manifests won't create namespaces, but the odh-operator will create.
