Update gloo.solo.io settings_v1 schema from Gloo Edge 1.21.3 CRD

[mkav-es]

The current gloo.solo.io/settings_v1.json lags the Settings CRD shipped with recent Gloo Edge versions. Valid manifests fail strict kubeconform validation with e.g.:

at '/spec/gateway/validation': additional properties 'fullEnvoyValidation', 'warnMissingTlsSecret' not allowed
at '/spec/gloo': additional properties 'istioOptions', 'enableAutoWebsocketTransformationPassthrough' not allowed
at '/spec/gloo/awsOptions/serviceAccountCredentials': additional properties 'region' not allowed

Regenerated with this repo's Utilities/openapi2jsonschema.py from the settings.gloo.solo.io CRD installed by the gloo-ee 1.21.3 Helm chart (openAPIV3Schema, version v1).

Verified: a rendered gloo-ee 1.21.3 release (69 resources) that previously failed now passes kubeconform -strict against the updated schema.
