docs: document Docker skip onboarding

CHANGELOG.md

@@ -9,6 +9,7 @@ Docs: https://docs.openclaw.ai
 - Channels: add Yuanbao channel docs entrance so the Tencent Yuanbao bot appears in the channel listing and sidebar navigation. (#73443) Thanks @loongfay.
 - Active Memory: add optional per-conversation `allowedChatIds` and `deniedChatIds` filters so operators can enable recall only for selected direct, group, or channel conversations while keeping broad sessions skipped. (#67977) Thanks @quengh.
 - Active Memory: return bounded partial recall summaries when the hidden memory sub-agent times out, including the default temporary-transcript path, so useful recovered context is not discarded. (#73219) Thanks @joeykrug.
+- Docker setup: add `OPENCLAW_SKIP_ONBOARDING` so automated Docker installs can skip the interactive onboarding step while still applying gateway defaults. (#55518) Thanks @jinjimz.
