feat: Implement Custom Footer

This commit replaces the default footer with a custom message. Currently,
it utilizes a fork of the 'jekyll-build-pages' action
(https://github.com/actions/jekyll-build-pages) due to an unmerged pull
request (pages-themes/primer#85). Once the pull
request is merged into the upstream, this change can be reverted.
