Poem

🐇 I hopped through docs with nimble feet,
Tucked a Discord bell where friends will meet.
A GitHub name, a helpful tip in sight,
Links stitched softly, morning bright.
Hooray — community takes flight! ✨

In `@docs/conf.py`:
- Around line 105-110: Replace the Discord channel URL in the social link
dictionary (the dict with "name": "NVIDIA NemoClaw Discord Forum") so it uses a
public invite URL (e.g., "https://discord.gg/INVITE_CODE") instead of the
channel-specific "https://discord.com/channels/{server_id}/{channel_id}"; update
the "url" value in that dict and, if you still want to reference the channel,
add explanatory documentation elsewhere that instructs users to join via the
invite before navigating to the channel link.
