docs: fix/add Placeholder to/in FluentAutocomplete Multiple = false #3916
Description
🙋 Documentation Request
FluentAutocomplete with Multiple=false uses Placeholder="Select a country" in the Razor example but that never shows in any browser I try.
Chrome renders with empty placeholder
input class="control" part="control" id="control" autofocus="" placeholder="" type="text" aria-controls="" aria-label="Select a country" autocomplete="off"
