Having a set of questions that are posed to every interviewee, regardless of their background, can be helpful when comparing candidates and in reducing unconscious bias (and the appearance of it, in case of lawsuit). Of course asking about GitHub specifically could be a signal of an ageism problem but I would hope your thoughtful answer would compensate in their minds for an absent or sparse GitHub account. It's reasonable for employers to seek people who are life-long learners. It's probably better for interviewers to ask a candidate about learning and growth rather than specifically something like GitHub but a savvy interviewee can recognize why such specific questions are asked and respond with other ways in which they've learned and grown, on company time or not.
