fix(subscription): update rsshub links (#146)

* chore(docs): update rsshub documentation URLs to https://docs.rsshub.app/routes/

Update rsshub-related documentation URLs to use the official documentation base URL.

Changes:
- Update bilibili feed URL generation in subscription-service.ts
- Update RSSHub documentation link in SubscriptionFormDialog.tsx to point to docs.rsshub.app/routes/

* chore(i18n): remove placeholder URL from i18n, use hardcoded URL instead

Remove the placeholders.url entry from all locale files and hardcode the
example URL directly in the SubscriptionFormDialog component. The placeholder
URL is a technical example and doesn't need internationalization.

Changes:
- Hardcode placeholder URL in SubscriptionFormDialog: "https://docs.rsshub.app/routes/youtube/user/@FKJ"
- Remove placeholders.url entry from all 14 locale files
