talosctl bootstrap fails on Azure Stack Hub about talos

[smira]

The core issue (I guess) is

[  188.818488] [talos] restarting platform network config {"component": "controller-runtime", "controller": "network.PlatformConfigController", "interval": "679.794804ms", "error": "error fetching metadata: 3 error(s) occurred:\n\tfailed to download config from \"http://169.254.169.254/metadata/instance/compute?api-version=2021-12-13&format=json\": Get \"http://169.254.169.254/metadata/instance/compute?api-version=2021-12-13&format=json\": dial tcp 169.254.169.254:80: connect: network is unreachable\n\tfailed to download config from \"http://169.254.169.254/metadata/instance/compute?api-version=2021-12-13&format=json\": failed to download config, status code 400, body \"{ \\\"error\\\": \\\"Bad request. api-ver\"\n\ttimeout"}

Yes, it appears that api-version is not supported in Azure Stack Hub.
