default to gcr on us3 when autopilot

[tbavelier]

What this PR does / why we need it:

• On GKE Autopilot, whitelisted Agent images are on gcr.io solely. When using US3 and not providing a registry, we default to Azure registry not whitelisted. We therefore add a condition on this defaulting to prevent using Azure if US3 and Autopilot.

Which issue this PR fixes

• fixes Failed to install Datadog Agent 3.90.2 in GKE Autopilot #1697

Special notes for your reviewer:

QA'd with:

1. Site is US3, Autopilot not provided (defaults to false)

╰─❯ helm template dd charts/datadog/ --set datadog.site=us3.datadoghq.com --set datadog.apiKey=foo | grep -i "image:"
        image: "datadoghq.azurecr.io/agent:7.62.0"
        image: "datadoghq.azurecr.io/agent:7.62.0"
        image: "datadoghq.azurecr.io/agent:7.62.0"
        image: "datadoghq.azurecr.io/agent:7.62.0"
        image: "datadoghq.azurecr.io/cluster-agent:7.62.0"
        image: "datadoghq.azurecr.io/cluster-agent:7.62.0"

2. Site is US3, Autopilot is provided

╰─❯ helm template dd charts/datadog/ --set datadog.site=us3.datadoghq.com --set providers.gke.autopilot=true --set datadog.apiKey=foo | grep -i "image:"
        image: "gcr.io/datadoghq/agent:7.62.0"
        image: "gcr.io/datadoghq/agent:7.62.0"
        image: "gcr.io/datadoghq/agent:7.62.0"
        image: "gcr.io/datadoghq/agent:7.62.0"
        image: "gcr.io/datadoghq/cluster-agent:7.62.0"
        image: "gcr.io/datadoghq/cluster-agent:7.62.0"

3. Site is something else, regular behaviour based on it:

╰─❯ helm template dd charts/datadog/ --set datadog.site=datadoghq.eu --set providers.gke.autopilot=true --set datadog.apiKey=foo | grep -i "image:"
        image: "eu.gcr.io/datadoghq/agent:7.62.0"
        image: "eu.gcr.io/datadoghq/agent:7.62.0"
        image: "eu.gcr.io/datadoghq/agent:7.62.0"
        image: "eu.gcr.io/datadoghq/agent:7.62.0"
        image: "eu.gcr.io/datadoghq/cluster-agent:7.62.0"
        image: "eu.gcr.io/datadoghq/cluster-agent:7.62.0"
╰─❯ helm template dd charts/datadog/ --set datadog.site=datadoghq.com --set datadog.apiKey=foo | grep -i "image:"
        image: "gcr.io/datadoghq/agent:7.62.0"
        image: "gcr.io/datadoghq/agent:7.62.0"
        image: "gcr.io/datadoghq/agent:7.62.0"
        image: "gcr.io/datadoghq/agent:7.62.0"
        image: "gcr.io/datadoghq/cluster-agent:7.62.0"
        image: "gcr.io/datadoghq/cluster-agent:7.62.0"
