Missing support for /websocket endpoint

[gem7008]

Description

At the official Pterodacyl API documentation, under Client (/api/client) and under Server (/servers/{server}), there are ~two~ one GET endpoint that is not exposed in pydactyl.

These endpoints are:

• GET https://pterodactyl.file.properties/api/client/servers/{server_id}/websocket
• ~GET https://pterodactyl.file.properties/api/client/servers/{server_id}/resources~

Benefits

It will grant two additional new features:

• the ability to get server stats
• the ability to read console logs

Resources endpoint isn't missing (https://pydactyl.readthedocs.io/en/latest/clientapi.html#pydactyl.api.client.servers.base.ServersBase.get_server_utilization).

Websocket is.
