CI: Revert 31323 for deprecation warning from Jedi
- [x] closes #31407

ipython/ipython#12102 has been solved, and the new release came out a couple weeks ago, so revert should be fine according to https://github.com/ipython/ipython/issues/12102#issuecomment-670987484

emm, seems with the latest version of ipython (7.17.0) and jedi (0.17.2), the deprecation warning is still there.

I converted this PR to WIP, and will ask in ipython issue again about this. Is this still active? emm, it is blocked by an ipython issue. my previous issue was closed ipython/ipython#12102 however, it wasn't being solved in the later version of ipython

there is a new issue  https://github.com/ipython/ipython/issues/12597 now tracking this warning issue, not sure if the fix will be included a newer version. what is the status here? @charlesdong1991 can you merge master and ping on green we have a *new* jedi issue, but this one is moot.
