enhancements:
  - |
    Refactor `PyPDFToDocument` to simplify support for custom PDF converters.
    PDF converters are classes that implement the `PyPDFConverter` protocol and have 3 methods:
    `convert`, `to_dict` and `from_dict`.
    The `DefaultConverter` class is provided as a default implementation.
deprecations:
  - |
    Using the `converter_name` parameter in the `PyPDFToDocument` component is deprecated.
    It will be removed in the 2.3.0 release.
    Use the `converter` parameter instead.
