Update governance test VAAs with corrected hex strings

- Updated test_set_fee_in_token, test_set_wormhole_address, test_authorize_governance_data_source_transfer, test_set_transaction_fee, and test_withdraw_fee with properly generated VAA hex strings
- 3 out of 5 tests now pass (test_set_fee_in_token, test_set_transaction_fee, test_set_wormhole_address)
- 2 tests still failing: test_authorize_governance_data_source_transfer (InvalidGovernanceMessage) and test_withdraw_fee (motsu framework ETH transfer limitation)
