Document debugging steps

[tamasfe]

Include steps to debug the lsp and cli described #280 on the website, so that people can contribute environment-specific information.

For reference:

The logs are in the OUTPUT panel, and then select Even Better TOML LSP in the dropdown.

To log pretty much everything you can use following settings, although it will be very noisy:

  "evenBetterToml.taplo.environment": {
    "RUST_LOG": "trace"
  },
  "evenBetterToml.taplo.extraArgs": ["--log-spans", "--verbose"],
