There was some confusion about how finfo works with complex numbers, leading to an issue being made requesting that numpy either adds a cinfo function or changes the documentation of finfo. The submitter of that issue also linked to an issue for a seperate repository, which also included conversation about the proposed change. (github.com/data-apis/array-api/issues/433) In both discussions, there was a general concensus that it would be better to change the documentation to explain how finfo works instead of creating a cinfo function.
Since this is just a small documentation change, there's no need to run the normal checks.
