add placeholder type list

[Zarkness2]

the placeholder of type list would be placeholder which would have a list inside example

  example:
    values:
    - "value 1"
    - "value 2"
    - "value 3"
    - "value 4"
    type: list

and they would be called like this %itsmyconfig_example_list_<position>%

where position would be the place of the text in this example to call the message value 4 would be with %itsmyconfig_example_list_4% and would return value 4 if you change the 4 by 2 would return value 2
