Is your feature request related to a problem? Please describe. Update Netly tags, because the package is hard found on nuget by topic search.

Describe the solution you'd like add websokets and others relevant tags to be found easy on nuget. e.g: netly socket sockets lib alec1o kezero ws websocket websockets websocket-server websocket-client client server ...

Describe alternatives you've considered N/A

Additional context Update tags on src/Netly.csproj Update nuget readme to contain websocket and http examples.
