ci: ignore nancy failre of rs/cors@v1.8.2 (bnb-chain#3327)

It is an issue reported in rs/cors#170 and
fixed by rs/cors#171, which was included in release
v1.11.0(Apr 2024): https://github.com/rs/cors/releases/tag/v1.11.0

But v1.8.2 was released in Dec 2021, which may have a lot difference.
And this vulnerability is limitted only to RPC nodes with maliciously configuration
in config.tion:
[Node]
HTTPCors = ["<malicious cors>",...]

So instead of upgrade to v1.11.0+, simply add it to nancy ignore for now
