Remove the `~/.arduinoProIDE/plugins` location as possible drop-in folder for VS Code extensions

[kittaakos]

Describe the problem

This is most likely a leftover before IDE2 went open source. I do not see any benefit supporting the above-mentioned folder as a possible location for VS Code extensions.

To reproduce

• Open IDE2 from a terminal and see the logs.
• IDE2 is looking for a drop-in folder under ~/.arduinoProIDE/plugins.

$datetime root WARN The local plugin referenced by local-dir:/path/to/home/.arduinoProIDE/plugins does not exist.

Expected behavior

IDE2 does not consider the arduinoProIDE folder as a plugin folder. Or arduinoIDE is used instead of arduinoProIDE.
