Improve visibility for deprecated commands on the Commands reference page

[sachinsinghsk13]

🧩 Description

Currently, on the Redis Commands documentation page, deprecated commands (for example, SUBSTR) appear visually identical to active commands.

As a user, this creates confusion — I only discover a command is deprecated after opening its detailed page. It would improve clarity and user experience if deprecated commands were visually distinguished on the main list.

✅ Proposed Enhancements

1. Add a “Deprecated” label or badge next to deprecated command names.
2. Optionally, use a different color tone or icon (e.g., faded or gray text) for deprecated commands.
3. Provide a tooltip or hover note linking to the preferred replacement command (e.g., “Use GETRANGE instead of SUBSTR”).
4. (Optional) Add a filter toggle like “Hide deprecated commands.”

💡 Why this matters

This change would:

Improve discoverability for new learners.

Reduce confusion around deprecated commands.

Encourage best practices (e.g., preferring GETRANGE over SUBSTR).

Provide a cleaner learning path for Redis 8.0 users.

Thank you for reaching out, @sachinsinghsk13. There are some good ideas here. I've added an internal ticket to track this request. Hopefully we'll get to it before too long.

I've modified the CSS and layouts, adding support for (1) and (3).

Thank you for delivering this feature so quickly, @dwdougherty . It'll really help new users learn about Redis by focusing primarily on active commands. ❤️

You're welcome, @sachinsinghsk13. Thanks again for the suggestions! I've made a note about the on/off switch to show/hide deprecated commands, and we may add that in a future enhancement.
