Broken url for feedback link at footer

[toto6038]

Problem description

There's a link "Comments, corrections or suggestions?" at the footer in each page, and the link points to the archived repository QBobWatson/gt-linalg. Since the repository has been archived, no new issues can be created and consequently the link opens GitHub 404 page.

The following code should have worked but not, maybe it's a deployment-related issue? https://github.com/QBobWatson/ila/blob/89587ee4dac9790b6fdf7d80dfce97d8d8f9d5ce/src/xsl/mathbook-html.xsl#L506-L525

Yeah, I found the link was broken as well for example here https://textbooks.math.gatech.edu/ila/least-squares.html
