Prepare 2.0.0-rc9.4 (#1411)

Although the Arduino IDE's primary preferences interface provides all required configuration capabilities, advanced
users may wish to fine tune the behavior of the application or temporarily enable additional log output to use for
troubleshooting problems with the IDE.

The IDE provides such settings in a separate interface.

Previously, the existence and access procedure for these settings was undocumented.

Since this is an advanced capability, the documentation is not appropriate for inclusion with the standard user
documentation on arduino.cc. A file here in the Arduino IDE is used instead. This file will serve as a container for all
such user-targeted documentation.

+
+The [**clangd** C++ language server](https://clangd.llvm.org/) and the [**ClangFormat** code formatter](https://clang.llvm.org/docs/ClangFormat.html) tool dependencies are managed in parallel. Updating them to a different version is done by the following procedure:

+1. Validate the **ClangFormat** configuration for the target version by following the instructions [**here**](https://github.com/arduino/tooling-project-assets/tree/main/other/clang-format-configuration#clangformat-version-updates)
+1. Submit a pull request in the `arduino/arduino-ide` repository to update the version in the `arduino.clangd.version` key of [`package.json`](package.json).
