fix(no-node-access): Improve detection logic in no-node-access to resolve imported aliases and setup instances

[y-hsgw]

As suggested in this comment, I’ve implemented a resolveToTestingLibraryFn utility inspired by eslint-plugin-jest’s parseJestFnCall.

Checks

• I have read the contributing guidelines.

Changes

• Introduced resolveToTestingLibraryFn, which improves accuracy by accepting a CallExpression node and resolving where it comes into the file — in other words, tracing it back to its original import source. This follows the same principle used in eslint-plugin-jest's parseJestFnCall.
• I’ve also created an accessors.ts module that parseJestFnCall depends on. It’s largely traced from the original implementation in eslint-plugin-jest.
• Addressed one of the concerns raised in issue no-node-access rule output false-positive warning after 7.5.0 release #1024:
  • userEvent.setup() instances with custom variable names (not just user) are now recognized and excluded from being flagged incorrectly (e.g., const userEvt = userEvent.setup(); userEvt.click(...) is no longer a false positive).

I understand this PR is a bit large—if it would help with the review process, I'm happy to split it into smaller parts. Please let me know if you'd prefer that.🙇‍♂️

@y-hsgw thanks! I'll try to review this during the week.

[Belco90]

I'm happy with the changes in general, but I'd like to think a bit more about the implications regarding the aggressive reporting.

I've added preliminary support for testing-library/utils-module in 6781117.
I hope this helps as a reference for further discussion.
Please feel free to let me know if it doesn't align with your expectations — I'm happy to revert if needed 🙇‍♂️

Thanks, this is great! I think it's fine and shouldn't overlap with the aggressive reporting for now. I'll give it another go and let you know if I can think of any improvement.

In the meantime, codecov is complaining about decreased code coverage so you can add some tests to cover that.
