fix e2e tests: gateway tls listeners must specify tls

[puertomontt]

Description

nightlies running GW API v1.0.0 were failing with :

The Gateway "<gateway created for test>" is invalid: spec.listeners: Invalid value: "array": tls must be specified for protocols ['HTTPS', 'TLS']

this PR adds the tls field for the listeners, which should be explicitly defined in the tests anyway, for clarity
