docs: fix broken link

[Bashmunta]

https://heartbeat.optimism.io - broken
https://status.optimism.io - correct

Summary by CodeRabbit

• Chores
  • Updated the default heartbeat endpoint to https://status.optimism.io (replacing https://heartbeat.optimism.io).
  • Deployments using default settings will now send health pings to the status service without requiring configuration changes.
  • Custom heartbeat URLs remain supported and unaffected.
  • This aligns monitoring with the publicly visible status page for clearer operational visibility.

Poem

A hop, a bop, a tiny tweak,
I nudge a URL this very week.
From heartbeat’s beat to status’ glow,
I thump my paws—onward we go!
Carrot-shaped pings in tidy rows,
🥕✨ small change made—the uptime shows.

181-181: Good catch: corrected default heartbeat URL.

Switching the default to https://status.optimism.io aligns with the working endpoint and fixes the broken link default.
