Ignore custom __repr__ for a dataclass

[MicaelJarniac]

I have a dataclass that inherits from a class that defines a custom __repr__.

Rich should be able to format dataclasses nicely, but I believe it's seeing that it already has a custom __repr__, and is choosing to use it instead.

The custom __repr__ returns a long string with no line breaks, though.

I wanted Rich to ignore it completely, and format it as if it was a normal dataclass with no custom __repr__.

I was actually using dataclasses indirectly, and the lib that created them was setting repr=False. Setting it to True solved my problem.
