text: Title: Docs: short (one-line) name for tutorials in sidebar
  Body: Names of tutorials in sidebar currently take up too much vertical space (see picture). Rather than displaying full title of each tutorial, would be better to only display an abbreviated one-line name in the sidebar. Eg. "Audio Classification with SpeechBrain and Cleanlab" could have short-name "Audio Classification" in the sidebar.
