fix(ci): stop a momentary 5xx on a valid link failing the lint job - #7083
Conversation
lychee never retries an HTTP 5xx response, so one 502/503/504 failed the whole MegaLinter job on unrelated PRs. Accept those codes in the gate and keep a real outage of the docs site visible through a retried daily availability check in the Maintenance workflow.

In @.github/workflows/maintenance.yaml:
- Line 61: Update the curl invocation near the retry options to enforce the
documented approximately three-minute retry window by adding a 180-second
overall retry limit, while preserving the existing per-attempt timeout and retry
behavior.
In `@lychee.toml`:
- Line 14: Update the lychee configuration’s accept list to remove the global
502–504 range, and use a scoped retry or equivalent mechanism that still fails a
URL after retries are exhausted. Preserve the existing accepted status codes and
ensure persistent 502, 503, or 504 responses remain detectable for every checked
URL.

48-63: 🎯 Functional CorrectnessThe workflow convention requires
mega-linter-runner -f go, but it does not prove that the command was skipped or failed. The inspected checkout contains no diff or validation failure for.github/workflows/maintenance.yaml. Repository learnings also indicate that workflow-only PRs are covered by the centralized lint job. This is only a generic validation reminder.

Why
A single momentary server error on any linked page fails the whole lint job, so unrelated PRs go red and need a manual re-run. The link checker never retries that kind of error, so tuning its retries cannot help.
What
The link check now treats a brief "server unavailable" answer as a valid link. Broken links (404), malformed URLs and persistent server errors still fail. So that a real outage of our own docs site is not hidden, a daily availability check with a few minutes of retries now runs in the Maintenance workflow.
Fixes #6398
