fix: Fix incorrect use of contract.update Update get_hashes_page.py

[0xwitty]

Description

In the remove_prefix_from_names function, the update() method was incorrectly used on the contract object. The update() method is not applicable to dictionaries in this context, as it expects a dictionary or key-value pairs, but remove_prefix returns a string, not a dictionary.

The corrected line now directly updates the contract['name'] key with the result from remove_prefix, like so:

contract['name'] = remove_prefix(contract['name'], 'openzeppelin_presets_')

This change ensures that the name field is properly updated without causing errors, improving the function's correctness.

Additional Notes

• The previous approach would lead to an error since contract.update(...) was attempting to assign a string to the dictionary in an incorrect manner.
• The new approach directly modifies the contract['name'] field, which is the intended behavior.

PR Checklist

• Tests
• Documentation
• Added entry to CHANGELOG.md
• Tried the feature on a public network

The update function also accepts an iterable object of key, value pairs, and that is what is receiving.
