Fix PEP-765 violation: return in finally block

[abhu85]

Summary

This PR fixes the PEP-765 violation reported in #9985 by moving the return True statement outside of the finally block in LocalDeleteRequestSubmitter._submit_transfer_request().

Problem

Python 3.14 (per PEP-765) emits a SyntaxWarning for return, break, or continue statements directly within finally blocks. The current code has:

finally:
    # Return True to indicate that the transfer was submitted
    return True

Solution

Move the return True after the try-except block. This preserves the exact same behavior (always returning True regardless of success or failure) while avoiding the warning.

Behavior Verification

• The function always returns True to indicate the transfer was submitted
• Success: queues QueuedResult and SuccessResult, then returns True
• Failure: queues QueuedResult and FailureResult, then returns True

Both existing tests (test_submit and test_submit_with_exception) verify this behavior and pass.

Test Plan

• All 5 existing TestLocalDeleteRequestSubmitter tests pass
• Verified no SyntaxWarning when importing the module
• Verified the AST check finds no remaining PEP-765 violations in awscli/

$ python -m pytest tests/unit/customizations/s3/test_s3handler.py::TestLocalDeleteRequestSubmitter -v
# 5 passed

Fixes #9985
