🐛 Fix APIExport SSA apply configuration client

[sttts]

Summary

The JSON tag for the permission claim GroupResource embedded struct was wrong. The apply configuration resulted in an object like the following:

{
    "apiVersion": "apis.kcp.io/v1alpha1",
    "kind": "APIExport",
    "metadata":
    {
        "name": "fabrics.upbound.io"
    },
    "spec":
    {
        "latestResourceSchemas":
        [
            "v240816-2328.projects.fabrics.upbound.io",
            "v240816-2328.services.fabrics.upbound.io",
            "v240816-2328.servicetiers.fabrics.upbound.io",
            "v240816-2328.spaces.fabrics.upbound.io"
        ],
        "permissionClaims":
        [
            {
                "GroupResource":
                {
                    "group": "tenancy.kcp.io",
                    "resource": "workspaces"
                },
                "all": true,
                "identityHash": "1422105e93411affc2d91b197e07d9168c1e7ca3b01fc6955b393122be112491"
            }
        ]
    }
}
