description:
tests/lint: document the fixed assertion failure for struct

The change to cgram.y 1.328 from 2021-07-15 didn't fix the crash on
purpose, it was merely a side effect.  The grammar rule that probably
fixed this was that the error handling now skips to the next T_SEMI,
which it didn't do before.
