cmnd format: wrong index for ShutterButton

[jdpiguet]

Describe the bug Using the "cmnd" format, the output of the ShutterButton commands is wrong (index starts at 0 instead of 1)

To Reproduce

1. Configure a Tasmota device as Shutter/Blind
2. Do a backup of the configuration (decode-config_linux --source x.y.z.t --backup-type dmp --backup-file /tmp/shutter)
3. Export the Shutter configuration from the file (decode-config_linux --source /tmp/shutter.dmp --output-format cmnd --group Shutter)
4. Check the " ShutterButton" lines, the index starts at 0 instead of 1

Expected behavior The index starts at 1
