BIP-371: use canonical PSBT_IN_TAP_KEY_SIG in invalid test titles

Correct two test-case headings that incorrectly used PSBT_KEY_PATH_SIG. The canonical Taproot key-spend field name is PSBT_IN_TAP_KEY_SIG (0x13) per BIP-371/BIP-174, so using PSBT_KEY_PATH_SIG was inconsistent and potentially confusing.
