Add Modrinth download single mod

[Felzow47]

Role

I play minecraft with clientside mod

Suggestion

I would like MultiMC to allow me to download mods from modrinth without having to go to the site and having to manually install the mod like forge, fabric, etc.

Benefit

no longer need to go to modrinth to look for the desired mod find the right version, download it, move it to the mod folder of the instance launch minecraft and realize that a dependency is missing return to modrinth download it try to launch minecraft again and finally it works if another dependency is not missing

This suggestion is unique

• I have searched the issue tracker and did not find an issue describing my suggestion, especially not one that has been rejected.

You may use the editor below to elaborate further.

it could be practical to simply update the mods for those who update often with just a single click,
automatically install dependency requested by mods
save time by avoiding having to fetch by hand each mod with dependency each time and put it in the folder, etc.
