feat: fill ctx.match and add ctx.commandMatch and node chores

[roziscoding]

• Allow users to get the "arguments" of a command using ctx.match
• Expose result of RegExp match through ctx.commandMatch

Example usage:

type MyContext = Context & CommandsFlavor;

const bot = new Bot<MyContext>("TOKEN");

const commands = new CommandGroup<MyContext>();

commands.command(/start ?(?<name>.*)?/, "a", async (ctx) => {
  console.log(ctx.commandMatch);
  // { command: /start ?(?<name>.*)?/, rest: 'name', match: ['start name', 'name'] }

  return ctx.reply(`Hello`);
});

bot.use(commands);

bot.start({
  onStart: () => {
    console.log("Bot started");
  },
});

Closes #58

I think, we should add fuzz tests

I don't really have the time for that right now, but I'd gladly review a new PQ :)
