Use the class name in the __repr__ implementations

[dlax]

Previously, the __repr__() method of those settings source classes was inherited from InitSettingsSource's thus returning a misleading 'InitSettingsSource(init_kwargs={})'. We here define a specific __repr__() method implementation for classes using a config file (json, toml, yaml).

Thanks @dlax for the PR. I left a comment

Thanks for the contribution. Instead, let's change the implementation of InitSettingsSource.__repr__ to:

    def __repr__(self) -> str:
        return f'{self.__class__.__name__}(init_kwargs={self.init_kwargs!r})'

init_kwargs

Then we will have JsonConfigSettingsSource(init_kwargs={}) for json config source. we don't have init_kwargs in this source.

Ah yes, well in this case probably best to keep it as is, but use self.__class__.__name__ for each __repr__ implementation to keep the class name and repr in sync

Ah yes, well in this case probably best to keep it as is, but use `self.__class__.__name__` for each `__repr__` implementation to keep the class name and repr in sync

I agree in general; but that's unrelated to this "fix" PR, in which I instead tried to conform to pre-existing patterns.

@dlax Please can you change all the __repr__ to and use self.__class__.__name__?

Please can you change all the `__repr__` to and use `self.__class__.__name__`?

Done through a separate commit.
