fix: remove node-ip dependency

[jwilson-anonyome]

Description of changes

Remove dependency on poorly maintained "ip" package, which has an open security advisory https://github.com/indutny/node-ip/issues/150

Implement an equivalent getLocalIpAddress() function that returns the first internal IP address. This is used by clients of the appsync-sumulator to connect to.
