fix(sharing): allow federated shares to non-trusted servers

When `showFederatedSharesToTrustedServersAsInternal` is enabled, the
trusted server filter was incorrectly applied to both internal and
external sharing sections. This prevented users from sharing with
federated users on non-trusted servers via the external share UI.

The filter now only applies to the internal section, allowing
non-trusted federated shares to appear in the external section.

Fixes: #56622
