Self-nominate for security release steward #1911

Following the previous nominations (#1764, #1233), I'd like to nominate myself as a security release steward.

Lately I've been much more involved in security triage and publication: I'm working on the OpenJS CNA integration (nodejs/security-wg#1576) and I am regularly part of the HackerOne escalations (from the CNA side).

I also plan to work more formally on preparing and reviewing security patches for Node.js core in the near future, as I already do for Undici.
