Extract local AS from peer xml

[mraerino]

When running this against an MX204 the local_as in bgp_session_info stays 0 - looks like the local ASN is on the peer level instead in this case:

<rpc-reply xmlns:junos="http://xml.juniper.net/junos/23.4R1-S1.5/junos">
    <bgp-information xmlns="http://xml.juniper.net/junos/23.4R0/junos-routing">
        <bgp-peer junos:style="detail">
            <peer-address>129.143.109.0+179</peer-address>
            <peer-as>553</peer-as>
            <local-address>129.143.109.1+63080</local-address>
            <local-as>215185</local-as>
