Improve language tag

Hi! As the model is multilingual, this is a PR to add other languages than English to the language tag to improve the referencing. Note that 29 languages are announced in the README, but only 13 are explicitly listed. I was therefore only able to add these 13 languages.

+Combine the three methods of **della**, **ties**, and **model stock** to merge the instruction model with the base model.

 The aim is to solve the problems of **the decline in instruction-following ability** and **mathematical ability** caused by using only the ties merging method or only the della merging method.
