[argocd] Bump ArgoCD version to 3.5.3 (#13591)

Argo CD publishes its tested Kubernetes versions at
https://argo-cd.readthedocs.io/en/stable/operator-manual/tested-kubernetes-versions/

3.5.3 is the latest available Argo CD release. Its matrix covers v1.33
through v1.36, which does not include the v1.37.1 shipped by this
branch, so this is the best available option rather than a combination
upstream has marked as tested. The 2.14 series is no longer listed on
that matrix.

argocd_version is derived from the first entry of
argocd_install_checksums, so adding the checksum for 3.5.3 at the top
of the list selects it.
