chore(deps): bump telegraf from 4.11.2 to 4.12.2

[dependabot]

Bumps telegraf from 4.11.2 to 4.12.2.

Release notes

Sourced from telegraf's releases.

v4.12.2

• Fix: session reference counter had defaulted to 0, therefore permanently being cached and never being cleaned up — this has been fixed.

v4.12.1

• Fix: bot.command did not match bot usernames if the registered username was not lowercased (#1809)

v4.12.0

Normally the most exciting features of a new release would be support for the latest Bot API. But in this update, it's session! This has been in the works for many months, and we're happy to bring it to you this release!

Some of you may know that builtin session has been deprecated for quite a while. This was motivated by the fact that session is prone to race-conditions (#1372). This left the community in a grey area where they continued to use session despite the deprecation, since no clear alternative was provided. Added to this was the fact that there were no official database-backed sessions, and all unofficial async session middleware were affected by #1372.

This release finally addresses both of these long-running issues.

🏃🏼 No more race conditions

#1713 provides a reference-counted implementation resistant to race conditions. Session is now no longer deprecated, and can be used safely!

Note: You should read more about how to safely use session in the docs repo.

™️ Official database adapters are here!

We're also happy to announce a revamped @telegraf/session—this provides official store implementations for database-backed sessions via Redis, MongoDB, MySQL, MariaDB, PostgreSQL, and SQLite. Just install the drivers necessary for your database, and off you go! Since this package now only provides a store implementation, it's usable with builtin session, and effectively makes all implementations have the same safety as the core package. Check it out!

🆗 Default session

Additionally, session now accepts a defaultSession parameter. You no longer need a hacky middleware to do ctx.session ??= { count }.

// 🤢 Old way
bot.use(session());
bot.use((ctx, next) => {
  ctx.session ??= { count: 0 };
  return next();
});
// 😁 New way ✅
bot.use(session({ defaultSession: () => ({ count: 0 }) }));

• Updated Typegram, added the following Markup.button helpers to request a user or chat:
• Markup.button.userRequest
• Markup.button.botRequest
