`doctest` should also print `Running` runner for consistent

Problem

test does print Running runner.

doctest does not print Running runner, which is not consistent.

Currently, cargo test delegates compiling, running, and reporting of doctests to rustdoc. For this to be fixed in the short term, that would be on rustdoc.

Long term, I'd like to make this less special and run like any other test which would resolve this. Keeping this open for now for that.

Note: #8889 may get rid of Running completely
