CI: fix CI failure for PDEP with status: Draft

This will only fix the CI failure, but 2 things to note:
1- The PDEP won't be shown in https://pandas.pydata.org/about/roadmap.html
2- If the PR gets the PDEP label, it will be considered as "Under Discussion" in the website roadmap
I want to fix that, but how will we differentiate? Do we check if the PR is marked as Draft? Or do we check if the PR has a certain label? (e.g. make a PDEP: draft label or use the needs discussion label)

I don't think we want to add draft PDEPs to the website but @datapythonista would know best

Going to mark this as ready for review as this fixes the CI failure.

As for the problem of draft PDEPs currently appearing in the website roadmap, the only fix I can think of is to make an API request for each opened PDEP PR and fetch the content of the PDEP file and see if the status is written as draft or not, but I will wait for @datapythonista's input before doing that as that is not the cleanest of solutions.

@WillAyd if you think it's appropriate, can we add some certain label to be able to differentiate between draft and under discussion PDEPs? If that's possible, then I can follow up with a very simple fix, otherwise I will just open an issue to not forget about this.
