Removed deprecated arguments from Bot class (#1494)

* Remove deprecated attributes from Bot class

The deprecated attributes `parse_mode`, `disable_web_page_preview`, and `protect_content` have been removed from the Bot class. Additionally, the associated warnings and test cases have been deleted. These attributes should now be passed using the `default=DefaultBotProperties(...)` syntax instead.

* Added docs and changelog

+===============
+Global defaults
+===============
+
+aiogram provides mechanism to set some global defaults for all requests to Telegram Bot API
+in your application using :class:`aiogram.client.default.DefaultBotProperties` class.
+
+There are some properties that can be set:
+
+.. autoclass:: aiogram.client.default.DefaultBotProperties
+    :members:
+    :member-order: bysource
+    :undoc-members: True
+
+.. note::
+
+    If you need to override default properties for some requests, you should use `aiogram.client.default.DefaultBotProperties`
+    only for properties that you want to set as defaults and pass explicit values for other properties.
+
+.. danger::
+
+    If you upgrading from aiogram 3.0-3.6 to 3.7,
+    you should update your code to use `aiogram.client.default.DefaultBotProperties`.
+
+Example
+=======
+
+Here is an example of setting default parse mode for all requests to Telegram Bot API:
+
+.. code-block:: python
+
+    bot = Bot(
+        token=...,
+        defaults=DefaultBotProperties(
+            parse_mode=ParseMode.HTML,
+        )
+    )
+
+In this case all messages sent by this bot will be parsed as HTML, so you don't need to specify `parse_mode`
+in every message you send.
+
+Instead of
+
+.. code-block:: python
+
+    await bot.send_message(chat_id, text, parse_mode=ParseMode.HTML)
+
+you can use
+
+.. code-block:: python
+
+    await bot.send_message(chat_id, text)
+
+and the message will be sent with HTML parse mode.
+
+In some cases you may want to override default properties for some requests. You can do it by passing
+explicit values to the method:
+
+.. code-block:: python
+
+    await bot.send_message(chat_id, text, parse_mode=ParseMode.MARKDOWN_V2)
+
+In this case the message will be sent with Markdown parse mode instead of default HTML.
+
+Another example of overriding default properties:
+
+.. code-block:: python
+
+    await bot.send_message(chat_id, text, parse_mode=None)
+
+In this case the message will be send withoout parse mode, even if default parse mode is set it may be useful
+if you want to send message with plain text or :ref:`aiogram.types.message_entity.MessageEntity`.
+
+.. code-block:: python
+
+    await bot.send_message(
+        chat_id=chat_id,
+        text=text,
+        entities=[MessageEntity(type='bold', offset=0, length=4)],
+        parse_mode=None
+    )
