Waiting for https://github.com/microsoft/FluidFramework/pull/11299 to be merged, that should take care of the "client packages" failed check about different versions between the new dependency on @fluid-tools/benchmark in the sequence package, and the one hoisted by Lerna based on the dependencies other packages have on it as well.
