Clarify FluentSelect SelectedOptionsChanged not triggered with manual options (#3670 and #1207)

📖 Description

This PR improves the documentation of the FluentSelect component by adding a clarification about the SelectedOptionsChanged event.

When using manual options, FluentSelect's internal data structure cannot be reliably updated. Because of that, the SelectedOptionsChanged callback will not be triggered.
This is a known limitation, and we do not foresee changes to this behavior in the short term.
