Enhancement suggestions / feature requests

Currently, we have Tekton version v0.44.0 installed by Civo marketplace as a newer version v0.50.0 is available, so it needs to be updated to the newer version. We kindly request an update to the latest version of Tekton on the Civo marketplace to ensure that we have access to the most recent features and improvements.
