Revise-test: make sure all workers load Revise (#36124)

This fixes the errors
```
julia> Base.runtests(["REPL", "cartesian"]; revise=true)
ERROR: LoadError: On worker 2:
UndefVarError: Revise not defined
```

and then later

```
julia> Base.runtests(["REPL", "cartesian"]; revise=true)
ERROR: LoadError: On worker 2:
UndefVarError: STDLIBS not defined
```
