Update some command pages to have interactive examples

[paoloredis]

Note

Low Risk
Documentation-only example formatting with no runtime, API, or build-logic changes beyond Hugo shortcode rendering.

Overview
Replaces static bash/redis-cli transcript blocks on several command reference pages with the {{% redis-cli %}} Hugo shortcode so readers get interactive examples instead of fixed redis> prompts and pasted replies.

Bloom (BF.*) and Cuckoo (CF.*) pages are updated in bulk: examples now list only the commands inside the shortcode (e.g. BF.ADD, CF.INSERT with options). Pages that had multiple highlight blocks—BF.RESERVE, BF.INSERT, CF.INSERT, CF.INSERTNX—use separate shortcode blocks per scenario so success vs error cases stay distinct.

Core commands DIGEST and HEXPIRETIME get the same treatment, moving from fenced code or plain blocks to redis-cli shortcodes. Command semantics and return-info sections are unchanged; only the Examples section format changes.
