Corrected typo without breaking backwards compatibility

[nuvious]

I noticed the note about the misspelled variable in #3029 which was mentioned in #2361 and #1861. The concerns about breaking backwards compatibility were important and actually sparked interest if this was resolvable. I sought to solve this issue while meeting the following requirements:

1. Does not introduce a breaking change
2. Informs the user via a warning of the deprecation ONLY if used in a named import
3. Does not make promises about when the old name will be removed; just mentions future release
4. Does not warn the user on general module imports

I used a mix of inspect functionality and very basic regex to achieve the above to the best of my understanding pending your review.

Python 3.8-3.12 local test using tox below; had a residual 3.13 environment that made me have to run it separately:

Python 3.13 test run separately after cleaning the 3.13 environment:

Ran pre-commit per the Contribution guide but it seemed to skip all the tests for some reason:

Also ran ruff independently on edited files:

Ran isort and neither file edited was modified, so that's good as well.

Below is the final result in terms of user experience if they attempt a module or named import:

May be a bit trivial, but below shows imports of the old variable name have changes reflected in the corrected one via pass by reference convention:
