Show check icon instead of edit icon when editing a list item

[nitinawari]

Description:
Currently, when editing a list item in the selectable list component (Teams & Groups), the edit (pencil) icon is always shown. This can be confusing for users, as there is no clear indication to accept/save the edit.

Update the UI so that when a list item is in editing mode, a check icon is displayed instead of the edit icon. Clicking the check icon should save the changes for that item.
