Code Review

This pull request updates the Go version to 1.25.7 and increments several dependency versions, including Tekton pipelines, OpenTelemetry, and various Kubernetes-related libraries. Feedback points out a discrepancy between the pull request description and the actual changes, specifically noting that intended security updates for the go-jose dependency are missing from the go.mod file.
