we want to mentioned that to filters become available in List endpoint, Product Filters has to be saved at least once in Control panel
and we have one limitation, validation is not implemented yet but we need to reflect this in docs :
we cant allow duplication, meaning its not allowed to save translation for filter if this name already exists
For example
Color -> Colir
Colorr - > Cant use Color or Colir here
