This is the wrong way to address this as it's a symptom of an underlying problem. The issue is how yarn.lock managed to get out of sync.

yarn.lock will get out of synch regularly not sure we want to waste time on this? At least I think it's ok to do that for nightly

[TomAFrench]

If yarn.lock is out of sync for nightly, it'll be out of sync for everything. Checking this is as simple as running a yarn install --immutable in another workflow.
