Describe the bug

Edit this with a clear and concise description of what the bug.

Provide a minimal code example that demonstrates the issue if you can. If the issue is visual in nature, consider posting a screenshot.

A weakref.proxy object can be used as the wrapped object when the object is not GC-ed. Then the object is finalized, the accessing the attributes of the weakref.proxy object will raise RefereenceError.

The weakref.proxy type has a proper __repr__ to handle the dead reference but rich traverse tries to inspec the proxy object and that will raise errors when the referenced object is gone.

In [1]: import weakref

In [2]: import rich

In [3]: class Foo:
   ...:     pass
   ...:     

In [4]: rich.print(weakref.ref(Foo()))
<weakref at 0x7f98d28b50d0; dead>

In [5]: rich.print(weakref.proxy(Foo()))
ReferenceError: weakly-referenced object no longer exists

In [6]: repr(weakref.ref(Foo()))
Out[6]: '<weakref at 0x7f98d0a80540; dead>'

In [7]: repr(weakref.proxy(Foo()))
Out[7]: '<weakproxy at 0x7f98d0a12070 to NoneType at 0x7f98d6516120>'
