This update incorporates the proposed version of lnprototest from
the patch [1], which includes the following fixes:
- Corrects the `ExpectError` event and updates BOLT 7 to expect a
warning instead of an error.
- Implements a new test for when the runner sends a bad signature
within the announcement_signatures message.
