ci: Warn (not error) on no-deprecated in vendored instrumentations

Vendored OTel instrumentations intentionally emit the old db.*/net.*
semantic conventions, whose local semconv constants carry the upstream
@deprecated JSDoc. The type-aware no-deprecated rule flagged every usage
as an error and failed the repo-wide lint. Downgrade it to a warning for
the vendored tracing paths so the intentional usage is surfaced without
breaking CI.
