Update the ql queries to account for change in how we look for runner
Previously, we guarded blocks of code to be run by the runner or the
action using if statements like this:
```js
if (mode === "actions") ...
```
We are no longer doing this. And now, the `unguarded-action-lib.ql`
query is out of date. This query checks that runner code does not
unintentionally access actions-only methods in the libraries.
With these changes, we now ensure that code scanning is happy.
