CI: Temporary fix to the docs build while we fix the ssh problems

[datapythonista]

Looks like the ssh key we have in the settings is not working as expected in #32074.

While we fix it (I don't have access to the settings, so can't check much), this prevents master from failing for the publishing of the dev docs to GitHub pages.

wait. so the new docs are failing but we didn't notice? just revert #32074

[datapythonista]

I can revert the failing changes, but it'll be hard to fix the problem if we're not trying to push the docs in the CI. The problem is that github secrets can't be accessed from PRs, so we can't test things using secrets before merging.

Not sure why github actions doesn't notify us when a build fails, but that's a good point, I'll open a ticket and investigate.

ok fair

merge away then

Thanks @datapythonista do we need/have an open issue for this?

[simonjayhawkins]

@datapythonista not sure this is working as intended. revert?

[simonjayhawkins]

@datapythonista nvm we now have green.

[datapythonista]

Yes, looks like this work as expected. The pushing to GitHub pages still failed, but the CI result is green:

• https://github.com/pandas-dev/pandas/actions?query=event%3Apush
• https://github.com/pandas-dev/pandas/runs/472871471?check_suite_focus=true#step:14:11

I created #32301 for the problem with the notifications. @jreback feel free to edit if that's not exactly what we should have. I also created #32303 for the original problem with the ssh key.
