ImportError: cannot import name 'update_default_config' from 'astropy.config.configuration'

Description: Encountering an ImportError when attempting to run a script or code relying on the fil_finder module. The issue arises due to the inability to import the 'update_default_config' function from 'astropy.config.configuration'.

Minimal code to reproduce:

from fil_finder import FilFinder2D
import astropy.units as u

Error message:

---------------------------------------------------------------------------

ImportError: cannot import name 'update_default_config' from 'astropy.config.configuration' (/home/<username>/anaconda3/envs/<env_name>/lib/python3.10/site-packages/astropy/config/configuration.py)

Installation Method:

pip install fil_finder

Additional Information:

Package	Version
astropy	6.0.1
astropy_healpix	1.0.3
astropy-iers-data	0.2024.4.8.0.32.4
fil-finder	1.7.2

Proposed Solution:

Given the deprecation of update_default_config and ConfigurationMissingWarning in the astropy.config module, as indicated in the official changelog of Astropy in astropy>=v6.0.0 , I propose to remove the import statement for update_default_config from the _astropy_init.py file within the fil_finder package directory. This has worked for me :)

Before:

from astropy.config.configuration import (
    update_default_config,
    ConfigurationDefaultMissingError,
    ConfigurationDefaultMissingWarning)

After:

from astropy.config.configuration import (
    ConfigurationDefaultMissingError,
    ConfigurationDefaultMissingWarning)

If deemed appropriate, I'm willing to create a pull request (PR) to implement this solution. Let me know your thoughts.
