fix(NcResource): use RouterLink where possible for internal shared resources

[Antreesy]

☑️ Resolves

• Reuse logic introduced in feat(NcRichText): handle internal links with Vue Router #5246 for Resource panel
  • Allows to navigate between shared sources within one app (Talk on example)
  • As logic is alreasy presented (getRoute() + NcButton::to), not considering it as breaking / feature for minor release
