Update Schematic format page

[rollerozxa]

AFAIK the schematic format page on the old Developer Wiki (which is at https://dev.luanti.org/luanti-schematic-file-format/ now) is a bit outdated, which led the author of MTSEdit to put their own documentation of the format here. The page should be updated cross examining the article in MTSEdit to see so that everything is correct.

Is the format now OFFICIALLY called "Luanti Schematic" or is that just a wiki artifact?

Because the file suffix ".mts" stands for "MineTest Schematic". (no, I'm not requesting to change the file suffix)

@Wuzzy2 Given that Minetest is now Luanti, it seems reasonable to refer to the format as "Luanti Schematic" with a disclaimer that the extension remains .mts for backwards-compatibility

Really just a Wiki artifact, the old page on the developer wiki for the spec was "Minetest Schematic File Format". But since there is another fully separate and wholly incompatible unofficial structure format used by the Minecraft community also called "schematics" it can be useful to be a bit more specific for new users who may think it is a compatible implementation, which it is not (this confusion has happened on the Discord server in the past).
