fix: Handling Dangling Commas in `delete_hanging_comma` Function

[varshith257]

/claim #416 fixes #416

Before the Change:

The function iterated through characters in the code string, checking and potentially skipping characters marked for deletion to_delete. This needed adjustment to handle dangling commas correctly.

After the Change:

• skips the dangling commas identified in to_delete, ensuring they are not included in the final result string.

Walkthrough

Walkthrough

The changes primarily enhance the control flow of the delete_hanging_comma function in inline_snippets.rs by adjusting the position of next_comma updates to occur before the loop. Additionally, a new test function, test_delete_hanging_comma, is introduced in test.rs to validate the corrected behavior of the delete_hanging_comma function, ensuring it effectively removes dangling commas in specified contexts.

@morgante This is a fix I am considering after analyzing the delete_hanging_comma function to handle dangling commas perfectly. Please review it.

If any changes or improvements needed, I am happy to incorporate them

[morgante]

@varshith257 I would be very surprised if this is sufficient to fix the issue. Please make sure you have added the test case from the issue and make sure all existing tests continue to pass as well.

[varshith257]

Yes, I think we need a test case better to test these changes. Will add it.
