Fix blurb import in the runpy interface

[webknjaz]

When blurb was being restructured, the import paths moved to deeper levels of the project layout. It was updated in the console scripts so invoking just the blurb command worked but python -m blurb didn't. This resulted in breaking the MSI installer smoke testing workflow in CPython's CI [1].

Blurb's own CI never invokes said interface, so it had no chance of catching the regression.

This patch corrects the import and adds a smoke test-style invocation of the affected interface.

Thank you!

I need this fix to release 3.13.0b4 asap. Any chance of a quick push to PyPI? Or should I edit the release scripts to pin to the older version?

[webknjaz]

I was hoping @hugovk would get to it yesterday, especially since publishing has been automated recently, so it should be a few button clicks mostly…

[zooba]

Looks like we're delaying the release by another day for other reasons, so slightly less of a hurry. But if it's not up by the time we restart builds I'll add a pin to 1.1.0 in the release scripts.

(edit: looks like 1.2.1 is in progress already, so I'm sure it's close)

@zooba FYI, you should be able to cut a release yourself by simply publishing a v1.2.1 @ https://github.com/python/blurb/releases (assuming you have enough privileges) and then, it'll magically appear on PyPI. The TestPyPI release published by merging this PR succeeded, so the release pipeline is healthy: https://github.com/python/blurb/actions/runs/9970205160/job/27548697808 / https://test.pypi.org/project/blurb/1.2.1.dev11/.

I went looking to see if I could hit the button myself, but it looks like Hugo is already working on it through #23, so I'll leave it there for now.

[webknjaz]

Sure, I figured. Just wanted to spell out how it works right now, just in case.

[hugovk]

You should be able to release, instructions in https://github.com/python/blurb/blob/main/RELEASING.md

But I'll do it right away.
