Add a version setting

[desbarmitar]

Add a minecraft version setting where the user can choose the version of the datapack.
Example: select "1.16" -> 6
select "1.15" -> 5
select "1.13" or "1.14" -> 4

This setting can be used to change the value of the datapack version in the file "pack.mcmeta"

I haven't decided if this is a good idea. I agree that it would be cool to have, but the problem is that it suggests that all versions are supported. Unfortunately, they are not. Maybe in the future, I will add more than just the latest version of all the features to this extension and then it makes sense to add the version selection. For now, I think, it is better not giving the user a choice. They can always set the version number in the pack.mcmeta manually.
