build(deps): bump github.com/cert-manager/cert-manager from 1.18.2 to 1.19.1

[dependabot]

Bumps github.com/cert-manager/cert-manager from 1.18.2 to 1.19.1.

Release notes

Sourced from github.com/cert-manager/cert-manager's releases.

v1.19.1

cert-manager is the easiest way to automatically manage certificates in Kubernetes and OpenShift clusters.

We reverted the CRD-based API defaults for Certificate.Spec.IssuerRef and CertificateRequest.Spec.IssuerRef after they were found to cause unexpected certificate renewals after upgrading to 1.19.0. We will try re-introducing these API defaults in cert-manager 1.20. We fixed a bug that caused certificates to be re-issued unexpectedly if the issuerRef kind or group was changed to one of the "runtime" default values. We upgraded Go to 1.25.3 to address the following security vulnerabilities: CVE-2025-61724, CVE-2025-58187, CVE-2025-47912, CVE-2025-58183, CVE-2025-61723, CVE-2025-58186, CVE-2025-58185, CVE-2025-58188, and CVE-2025-61725.

@dependabot ignore this minor version

Cert-manager recently updated its gateway-api dependency to v1.4.0, and this update propagates to Contour when cert-manager is bumped, causing compilation to fail. The version is newer than what Contour currently supports.

In Contour, cert-manager isn’t a dependency of the contour binary itself, but it is only used in the e2e test suite for generating certificates using the Go types from its CRD API. However, that dependency now determines which gateway-api version Contour ends up using.

OK, I won't notify you about version 1.19.x again, unless you re-open this PR.
