Make Telemetry "Opt-in"

[madflow]

Feature description or problem with existing feature Telemetry is currently set to "Opt Out".

Describe the solution you'd like Make Telemetry "Opt In" and explain maybe why it would be helpful to enable it.

Additional context I use Neovim and have to disable Telemetry like so:

return {
  --- https://github.com/neovim/nvim-lspconfig/blob/master/doc/server_configurations.md
  {
    "neovim/nvim-lspconfig",
    opts = {
      servers = {
        intelephense = {
          settings = {
            intelephense = {
              telemetry = {
                enable = false,
              },
            },
          },
        },
      },
    },
  },
}
