Removed beartype (#3528)

### What problem does this PR solve?

The beartype configuration of
main(64f50992e0) is:
```
from beartype import BeartypeConf
from beartype.claw import beartype_all  # <-- you didn't sign up for this
beartype_all(conf=BeartypeConf(violation_type=UserWarning))    # <-- emit warnings from all code
```

ragflow_server failed at a third-party package:

This third-package is out of our control. I have to remove beartype
entirely.
