Remove take action from CI

[WillAyd]

The take action in github is well intentioned, but may be causing more harm than good. Often users comment "take" but progress immediately stalls, and new contributors can be discouraged from pursuing issues that are already assigned to users.

As an alternative, we can document better expectations for "soft reserving" an issue, much like sci-kit learn has done in scikit-learn/scikit-learn#31568

Forgot to mention but credit to @mroeschke for the idea - it wasn't mine :-)

+1, I agree. Also, maybe only members should be able to assign someone to avoid confusion.

+1, a problem that I found was users were able to "take" but arent able to "unassign" themselves in an issue
