Recent failures with v1 recipe grayskull updates

[janjagusch]

I'm currently observing more and more failures with the grayskull updater for v1 recipes. On the update PR, you will see the internal error message: 'We couldn't run dependency analysis due to an internal error in the bot, depfinder, or grayskull. :/ Help is very welcome!'

Here' a sample of affected feedstocks:

• [bot-automerge] dominodatalab v2.0.0 conda-forge/dominodatalab-feedstock#22
• [bot-automerge] tabpfn v6.0.6 conda-forge/tabpfn-feedstock#34

Inside the update workflow, we see this trace:
