refactor(service-worker): remove redundant argument to `versionFailed()` (#31865) 

The `latest` argument was only ever set to the value of comparing
`this.latestHash` with the `appVersion` hash, which is already computed
inside `versionFailed()`, so there is no reason to pass it as an
argument as well.

This doesn't have any impact on the current behavior of the SW.
