Fix testthat checks on Windows

[AlexAxthelm]

          Note: Windows checks seem to be failing due to the breaking change to `r2dii.data` that introduced the new `increasing_or_decreasing` dataset. 

I don't really understand why only the windows checks fail, since in principle the same checks should be applied to R-CMD-check/macos-latest... in any case, I believe it is unrelated to this PR.

Example of failing checks:

It looks like the failing checks are installing v 0.3.1 of r2dii.data

while the passing window check (latest) is installing 0.4.1 (which is expected).

Hmmm, do you have any idea why that would be? I find that strange. I wonder if it has to do with the posit package manager being down?

[AlexAxthelm]

Looks like. I see that you reran the action and it ran clean. https://github.com/RMI-PACTA/r2dii.plot/actions/runs/8001784071/job/21853669742?pr=552#step:5:3293

Closing this, but maybe you want to wrap those tests in a check on r2dii.data version?

I'm thinking the bug was because posit package manager was down, so it was trying to install from a sub-par repository mirror. Now that it is back up, things work as expected!
