[fix] doc: drop the contents:: directive, name the plugin consistently

Furo renders its own page-local table of contents and reports an error
when a page adds one with contents::.  No other page in the tree uses
that directive; these two now follow suit.

The plugin is named "AI Summary" where the name of the plugin is meant,
and "AI summary" where the generated text itself is meant.  That also
fixes the entry in the plugin navigation, which takes its label from the
page title.

Two references to the configuration page rendered as its title, the bare
YAML key "ai_summary:", which reads as a typo in a sentence.  They now
carry explicit link text.
