Handle unusual __qualname__ in inspect
<!--
Please note that Rich isn't accepting any new features at this point.
If a feature can be implemented without modifying the core library, then
they should be released as a third-party module. I can accept updates to the
core library that make it easier to extend (think hooks).
Bugfixes are always welcome of course.
Sometimes it is not clear what is a feature and what is a bug fix.
If there is any doubt, please open a discussion first.

## Description
I discovered, that an object with an unusual `__qualname__` attribute (not a `str`, e.g. a descriptor) causes `inspect` to fail.
This can happen if an object is created this way intentionally, but I discovered it, when decorating a class with `@functools.lru_cache` which forwards the underlying attributes using a descriptor when it can't add the to it's `__dict__` because the class uses `__slots__`:
```python
from functools import lru_cache
from rich import inspect
@lru_cache
class Klaas:
__slots__ = ("__qualname__",)
if __name__ == "__main__":
from rich.traceback import install
install()
inspect(Klaas.__qualname__)
inspect(Klaas, all=True)
```
I fixed it by checking the type of `__qualname__` falling back to `__name__` and if that isn't a `str` using the already provided fallback.
