test: new test case for renaming JS Object (#38361)

## Description

This PR adds a test case for the bug:
https://github.com/appsmithorg/appsmith/issues/38207

This PR tests the issue where renaming a JS Object via the context menu
caused the focus to shift to another tab in the editor.

Changes:

- Added test cases to validate that focus remains on the current tab
while renaming JS Objects.
- Verified the functionality by renaming multiple JS Objects and
ensuring the changes are reflected without altering tab focus.
