docs: document description field for dynamic interactive message list options

[SangeetaMishr]

Summary

Fixes #657

glific/glific#4142 (merged via glific/glific#5399 on July 21) added support for populating a WhatsApp list option's description from a variable - previously only the title/label could be set dynamically, and the description field was always left blank in dynamic interactive messages fed from a Google Sheet.

This updates the existing "Dynamic Interactive Messages via Google Sheet" doc (which already covered the ID/Variable setup) to document the new Description field:

• Step 1: note that you can add extra sheet columns for descriptions
• Step 5: added a Description column to the ID/Variable example table, explained it's optional and list-message-only (reply buttons have no description), and noted WhatsApp's 72-character limit (verified against the backend's trim_field(param["description"], 72))

Also added a short cross-reference from the related "List options in Interactive Messages" doc, which documents the same ID/Variable config pattern in a different use case, so it doesn't go stale relative to this change.

Verification

Confirmed end-to-end against the actual code rather than just the issue text:

• glific/glific PR #5399: backend now reads param["description"] and trims it to 72 chars
• glific/floweditor's SendInteractiveMsgForm.tsx: the node config form already has an id/variable/description field triplet per row (placeholders id {n}, variable {n}, description {n}), so this is a fully shipped, usable feature end-to-end, not just a backend change

Test plan

• Docs site renders the updated tables and sections correctly
• Reviewer confirms the Description field placement/behavior matches the current flow editor UI

1. the screenshot of the dynamic interactive message node needs to be updated to show that there is not a description field,
2. Screenshot of the google sheet which shows the description field needs to be added
