e2e-test: improve handling of open folder options (#6331)

### Summary
So I previously just fixed this, but I didn't account for the fact that
in CI full test suite runs specifically there are A LOT of temp dirs,
therefore the max of 50 options (which I had set) is not enough. Rather
than extending that, I opted to type each dir of the path sequentially
and wait for list to load.

### QA Notes

[Running full
suite](https://github.com/posit-dev/positron/actions/runs/13297607899)
to confirm all is well.
