fix(argo): quote test-name parameter values to satisfy strict YAML parsers

The unquoted test name string contains '::' (Rust path separator). Some
strict YAML implementations (Go go-yaml when used by certain kustomize
paths) interpret it ambiguously. Quoting makes it always a string scalar.

Templates were applied directly via 'kubectl apply -f' which uses a
permissive parser; the unquoted form worked. Quoting makes them
also kustomize-compatible.
