behavior: ctx.getNearestCommand only being able to lookup one Commands instance at the time

[carafelix]

Since the plugin allows to organize commands into multiple and diverse Commands instances, would make sense to allow

getNearestCommand: (
        commands: Commands<C>,
        options?: Partial<JaroWinklerOptions>,
    ) => string | null

to search across a Commands array. Internally should be adjusted for that too.
In any case this could be kept as it is since it's possible to do something in the lines of:

bot
.filter(Context.has.filterQuery("::bot_command"))
.use(async (ctx) => {
 let suggestedCommand
 for(const commands of [userCommands, adminCommands]){
   const search = ctx.getNearestCommand(commands)
   if(search){
     suggestedCommand = search 
   }
 }

 if (suggestedCommand) {
   return ctx.reply(
     `Hmm... I don't know that command. Did you mean ${suggestedCommand}?`,
   );
 }
 await ctx.reply("Oops... I don't know that command :/");
});

But this is not ideal since fuzzySearch does not expose its returned value similarityThreshold. That could be exposed and let users do whatever logic they want or managed internally and return the most similar command.
Also prefix of the best match should be exposed too
