Rename `build-without-cache` to `build-without-secrets` (#199)

This workflow uses the public cache. It just can't update it. The goal of this workflow is to see how public forks behave. The name is a vestige from when we didn't have a public cache. But the original goal was always to see how public forks and external repos would behave.
