chore: track `module` usage in telemetry

[matifali]

We publish plenty of terraform modules to be used with templates at https://registry.coder.com/modules. We need to track them in telemetry to better know the value of registry.coder.com before investing any more resources in it

We should be able to track the module name source, and the version if any.

For example to track

module "jetbrains_gateway" {
  source          = "https://registry.coder.com/modules/jetbrains-gateway"
  version         = "1.0.0"
  agent_id        = coder_agent.main.id
  agent_name      = "main"
  folder          = "/home/coder/coder"
  jetbrains_ides  = ["GO", "WS"]
  default         = "GO"
}

we need source, version, and name i.e. jetbrains_gateway.
