Add Windows-specific tip for creating config.toml file in documentation

Nobody has claimed this yet.

Hi guys,

https://docs.massa.net/docs/node/routability
Under : edit the file massa-node/config/config.toml (or create it if absent) with the following contents:

I would add :

Creating the config.toml file if it doesn’t exist (Windows tip) "You can use a toggle button so that the tip only appears when the user clicks on the sentence."

- Open the Notepad
- Save As : When choosing the name for the file, follow these steps :
Start by typing * in the File name field and press ENTER.
This will allow you to choose a specific extension.
Now, delete the * and type the full name config.toml.
In the "Save as type" dropdown, select All Files.
Save the file in the massa-node/config/ directory.

(This method ensures that Windows properly creates the file with the .toml extension, rather than saving it as a .txt file.)

Open the documentation page at https://docs.massa.net/docs/node/routability and locate the config.toml creation instructions. Add the Windows-specific Notepad steps in a toggle or tip, then verify that the instructions render correctly and explain how to avoid creating a .txt file.
