CI:
audit-deps failed on all platforms - a known issue.
audit-network failed on Linux - a known issue.
Everything else passed.

@mkarolin looks like the only one that failed that's a bit surprised is audit-network as per https://ci.brave.com/job/pr-brave-browser-84.0.4147.85-1.11.x/3/execution/node/475/log/. I'm not 100% sure if the above is worth restarting but haven't seen that failure in a while.

Other than the above one, the remaining are audit-deps failures due to lodash which is a known issue and fixed in 1.12.x and 1.13.x 👍

Uplift into 1.11.x approved after deliberating with @brave/uplift-approvers.
