[Feature request] Add architectury api dependency declaraction

[sashafiesta]

I've created an issue to remind you that starting a mod without architectury api will cause a crash. It's better to add dependency in mods.toml and fabric.mod.json to show user an error when architectury api is missing.

Sorry, I can't do a pull request right now, but I hope this reminder helps.
