Updating domain, author, favicon, CI & fixing page links for new Hugo version
A few fixes and small improvements :
- Updating domain to solidaires-informatique.ovh
- Changing author to "Solidaires Informatique OVH" in the config and hiding it in the pages
- Improving SEO by setting social media and search engines tags in header.
- Switching all links to logical paths (old syntax is broken in latest Hugo) as advised on Hugo's GitHub. See https://gohugo.io/methods/page/path/#monolingual-site for syntax instructions.
- Adding separate GitLab CI build for all branches/merge requests
