There was a thread somewhat related to this recently. I’m wary of having anything that’s not direct professional experience directly listed in the resume.
The consensus is just that outside rare occasion or notability in your field, no one cares about your blog/project/GH/etc.
If I mentioned it directly on a CV at all I would list it in the very small personal interests section at the end along with my other hobbies (running, HEMA, etc.). I've not needed to update my CV in a long time, so advice on this may have changed, but way back when I last touched it up it was worth including such a short list of “what I do in my spare time” and interviewers would sometimes pick something off that as a starting point for a bit of informal discussion.
Though of course it will be linked from my main “vanity page” (which also doesn't currently exist in any touched-in-the-last-decade form) at forename.surname.net or similar, which would be listed on my CV along with other contact details, as well as being linked to on other relevant online profiles. An interested employer might look, those that don't care won't be affected either way.
