fix: Correctly handle different invoice types to prevent crashes

Resolved a bug where the `Invoice` class would raise an `AttributeError` when parsing invoice data from payment links. This was due to the rigid expectation of `title`, `description`, and `start_parameter` attributes, which are not always present in the raw `Invoice` object returned by the Telegram API.

- Modified the `Invoice` class in `pyrogram/types/payments/invoice.py` to make `title`, `description`, and `start_parameter` optional.
- Updated the `_parse` method to handle both `raw.types.MessageMediaInvoice` and `raw.types.Invoice` types, ensuring that missing attributes are handled gracefully.
