(maint) Extend delay for acceptance testing

Previously the acceptance tests were intermittently failing on Windows GitHub
Actions runners. I really don't like this. But unfortunately the workspace
symbol loading is asynchronous so you don't _really_ know what it's available.
We could add another Request or extend puppet/getVersion to emit whether the
workspace has been loaded yet.  In the meantime just sleep a long time and hope
it's loaded by then.
