calls using get_grouplist(SETTINGS[0][2]) use latest device version, not configured device version

Describe the bug In output_tasmotasubcmnds(): https://github.com/tasmota/decode-config/blob/7584caf4c859ed5ad66653369e11cdcc5d510513/decode-config.py#L4828 creates groups based on the latest device version, which may create invalid commands for a device/file using an earlier version. I believe that the appropriate template has already been determined and is in CONFIG['info']['template'] and should be used instead.

SETTINGS[0][2] is also in the argparser: https://github.com/tasmota/decode-config/blob/fad988d9c5662b103abab495a77e75f07fc5e050/decode-config.py#L5067 but can't be replaced as CONFIG hasn't been defined yet. This could mean that invalid commands are suggested by the argparser help. This seems non-trivial to fix and a minor corner-case. I'd suggest ignoring the issue here (or maybe just including a note such as "some commands may not apply to devices/file with earlier versions of Tasmota")

To Reproduce Using device with version 8.5.1:

% ./decode-config.py -s tasmota-ABC123.dmp --output-format cmnd --group Serial -v
INFO: Load data from file 'tasmota-ABC123.dmp'
INFO: File 'tasmota-ABC123.dmp' is using Tasmota v8.5.1 on ESP82xx
<strindex> out of range [0, 87] in <fielddef> (15, '699s', (23, 87), ([8], None, ('Management', '"SwitchText{} {}".format(#+1,"\\"" if len($) == 0 else $)')))
<strindex> out of range [0, 87] in <fielddef> (15, '699s', (23, 95), (None, None, ('Light', None)))
<strindex> out of range [0, 87] in <fielddef> (2, '699s', (23, 87), ([28], None, ('Management', '"SwitchText{} {}".format(#+1,"\\"" if len($) == 0 else $)')))

# Serial:
  Baudrate 460800
  SBaudrate 38400
  SerialConfig 8N1
  SerialDelimiter 255
  TCPBaudrate 0

Expected behavior replacing line 4828 with: groups = get_grouplist(CONFIG['info']['template']), avoids the <strindex> out of range errors.
