website: Update Hugo #1424
Description
The website uses Hugo 0.110.0, which is rather outdated at this point. Building it with a recent version (0.147.7 as of now) causes the build to fail due to deprecated features being used:
ERROR deprecated: resources.ToCSS was deprecated in Hugo v0.128.0 and subsequently removed. Use css.Sass instead.
ERROR deprecated: .Site.Social was deprecated in Hugo v0.124.0 and subsequently removed. Implement taxonomy 'social' or use .Site.Params.Social instead.
Low prio, but I think it should at least be written down somewhere.
