I fixed stale links in six Docs pages. Guide links now include the Docs
base path, and links to the old Database Hooks route point directly to
the Dashboard Webhooks page.
## To test
- Open the Logs ingest guide in the Docs preview and follow the updated
guide links. Each destination should load.
- Open each affected Docs page in the preview and follow its Webhooks
link. The Dashboard Webhooks page should load after sign-in.
## Linear
- fixes GROWTH-1301
