Rename pio folder to pio-tools solve linux build errors

When vscode is ran from the Tasmota folder in Linux, build fails with message :
```Executing task: pio run <
    The terminal process failed to launch: Path to shell executable "pio" is not a file of a symlink.```
Renaming pio folder into pio-tools solve the problem.

Note: the problem can still occur if the user have a pio folder in his PATH...
