[Bug Report]: Microsoft.Network/vpnGateways/connections] `ConnectionBandwidth` property has been deprecated

[chris5287]

Describe the bug

It appears the ConnectionBandwidth property has been deprecated, but the ARM docs haven't been updated here: https://docs.microsoft.com/en-us/azure/templates/microsoft.network/vpngateways/vpnconnections?tabs=bicep#vpnconnectionproperties

This means deployments fail and there is no way to use the module as it has a default value in the bicep file :(

To reproduce

https://github.com/Azure/ResourceModules/blob/80c29bd5fef1d522354b801b6bb59106e74ad67c/modules/Microsoft.Network/vpnGateways/connections/deploy.bicep#L38

Code snippet

module vpnc 'main/modules/Microsoft.Network/vpnGateways/connections/deploy.bicep' = {
  name: '${deployment().name}_vpnc'
  params: {
    name: 'vpnGatewayConnection'
    vpnGatewayName: 'vpnGateway'
    remoteVpnSiteResourceId: 'remoteVpnSiteResourceId'
    vpnLinkConnections: [...]
  }
}

Relevant log output

{
    "status": "Failed",
    "error": {
        "code": "VpnConnectionPropertyIsDeprecated",
        "message": "Update request for VpnConnection /subscriptions/....../resourceGroups/..../providers/Microsoft.Network/vpnGateways/..../vpnConnections/.... contains deprecated property ConnectionBandwidth. Please use corresponding VpnSiteLinkConnection property instead.",
        "details": []
    }
}

@chris5287 I'm having trouble reproducing the issue. The module deployment using module pipeline worked for me, also changing the "ConnectionBandwidth" property was successful. Can you please share more details, which could help me to reproduce the issue? For example: In which region are you deploying, are you using the latest version of the modules?

I was using 0.6.0 deploying into the uksouth and canadacentral regions
