Deprecate force_sms and sign_up

Browse Source 
On the 10th of February, Telegram sent the following message to
those with an application registered on https://my.telegram.org.

Telegram API Update. Hello [REDACTED]. Thank you for contributing to the
open Telegram ecosystem by developing your app, [REDACTED].

Please note that due to recent updates to Telegram's handling of SMS and
the integration of new SMS providers like Firebase, we are changing the
way login codes are handled in third-party apps based on the Telegram API.

Starting on 18.02.2023, users logging into third-party apps will only be
able to receive login codes via Telegram. It will no longer be possible
to request an SMS to log into your app - just like when logging into
Telegram's own desktop and web clients.

Exactly like with the Telegram Desktop and Web apps, if a user doesn't
have a Telegram account yet, they will need to create one first using
an official mobile Telegram app.

We kindly ask you to update your app's login and signup interfaces to
reflect these changes before they go live on 18.02.2023 at 13:00 UTC.

This change will not significantly affect users since, according to our
research, the vast majority of third-party app users also use official
Telegram apps. In the coming months, we expect to offer new tools for
third-party developers that will help streamline the login process.

In that case, we have bad news for you. Telegram is much more likely to ban
these numbers, as they are often used to spam other accounts, likely through
the use of libraries like this one. The best advice we can give you is to not
abuse the API, like calling many requests really quickly, and to sign up with
these phones through an official application.

We have also had reports from Kazakhstan and China, where connecting
would fail. To solve these connection problems, you should use a proxy.

**By using this method you're agreeing to Telegram's
Terms of Service. This is required and your account

Arguments
code (`str` | `int`):
The code sent by Telegram
first_name (`str`):
The first name to be used by the new account.
last_name (`str`, optional)
Optional last name.
phone (`str` | `int`, optional):
The phone to sign up. This will be the last phone used by
default (you normally don't need to set this).
phone_code_hash (`str`, optional):
The hash returned by `send_code_request`. This can be left as
`None` to use the last hash known for the phone to be used.
Returns
The new created :tl:`User`.
Example
.. code-block:: python
phone = '+34 123 123 123'
await client.send_code_request(phone)
code = input('enter code: ')
await client.sign_up(code, first_name='Anna', last_name='Banana')
This method can no longer be used, and will immediately raise a ``ValueError``.
