Add a patch to disable graph 70 in graph atlas tests

This test seems to cause arbitrary failures.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

The lack of a python 3.10 for linux-64 is causing me trouble downstream: https://github.com/conda-forge/mpas_tools-feedstock/pull/52

@sodre and @vtraag, this seems to be working (2 more tests still to go as I write this). Obviously, hard to be sure since the previous failures appear to have been pretty random. Let me know if you are okay with the patch approach or if you'd prefer something else.

[vtraag]

Great, looks good to me @xylar! Thanks for being willing to also help maintain this feedstock.

@vtraag, shoot! We're still seeing exactly the same error as before in some builds after this got merged:

During handling of the above exception, another exception occurred:

It's still referring to graph #70 even though I thought I assigned that one to the list to be skipped. Any idea why it didn't work?

I'm manually re-running the 2 failed tests but a better fix is still needed.

[vtraag]

Hmm, annoying, I would in principle expect it to work indeed. I don't have an idea directly, I'd need to check it out in more detail.

[vtraag]

Ah, it's already clear, it's not being handled for Hubs, I'll correct it and push it shortly.
