ParamsDict represents the class object itself, not keys and values on Task Instance Details #25295

Apache Airflow version

2.3.3 (latest released)

What happened

ParamsDict's printable presentation shows the class object itself like <airflow.models.param.ParamsDict object at 0x7fd0eba9bb80> on the page of Task Instance Detail because it does not have __repr__ method in its class.

It used to be dict object and what keys and values Params include are shown on UI before replacing Params with the advanced Params by #17100.

What you think should happen instead

It was originally shown below when it was dict object.

I think it can be fixed by adding __repr__ method to the class like below.

class ParamsDict(dict):
    ...
    def __repr__(self):
        return f"{self.dump()}"

How to reproduce

I guess it all happens on Airflow using 2.2.0+

Operating System

Linux, but it's not depending on OS
