refactor: Remove external libraries as they are hosted in our Conan Center Index fork (#5643)

This change:
* Removes the patched Conan recipes from the `external/` directory.
* Adds instructions for contributors how to obtain our patched recipes.
* Updates the Conan remote name and remote URL (the underlying package repository isn't changed).
* If the remote already exists, updates the URL instead of removing and re-adding.
  * This is not done for the libXRPL job as it still uses Conan 1. This job will be switched to Conan 2 soon.
* Removes duplicate Conan remote CI pipeline steps.
* Overwrites the existing global.conf on MacOS and Windows machines, as those do not run CI pipelines in isolation but all share the same Conan installation; appending the same config over and over bloats the file.
