Prior to this change only multi-selection dropdown could be cleared.
This change makes `update_dropdown_input` behavior analogous to
`shiny::updateSelectInput`.

Note: this is a breaking change. Prior to this commit updating with
`character(0)` or `""` did not have any effect.

Expected `update_dropdown_input` behavior:
- choices != NULL and value == NULL changes choices and clears selection
- choices != NULL and value != NULL changes choices and sets selection
- value == "" and value == character(0) clear the dropdown
- Providing a value not present in choices doesn't change the selection

The behavior is uniform between a single-selection and a multi-selection
variants.

Note:
- an empty single-selection `dropdown_input` returns "" (no changes)
- an empty multi-selection `dropdown_input` returns NULL (no changes)

458 dropdown clear

Pre release changes 0.5.1

Upon removal, an organization-wide template will be used. The template
is stored in Appsilon/.github repository.
