meilisearch: show keys by name not description

This makes show-key’s output match our documentation as of Meilisearch
1.8.0-8-g4d5971f343c00d45c11ef0cfb6f61e83a8508208. Since I’m not sure
if older versions maybe only provided description, it will fallback to
the latter if no name parameter exists.
