deny: Ignore GHSA-hcp2-x6j4-29j7 to unblock CI. (#42203)

This vulnerability is just issued 3 hours ago. It is patched in
>=0.1.0-rc.3, but we tried last week: it takes significant effort to
upgrade:
https://github.com/servo/servo/pull/42120#issuecomment-3793543197

Given that it blocks the CI, no exploit is known yet, and the high
attack complexity, we should ignore it for now.
