#24744 Converted ./components/spinner_button.tsx from Class Component to Function Component (#24804)

* Converted [./components/spinner_button.tsx] to functional component

* Converted [./components/spinner_button.tsx] to functional component

* [./components/spinner_button.tsx]: wrapped the component with react.memo + removed default props + use multi-lines in args

* [./components/spinner_button.tsx]:
- fix lint errors in spinner button
- fix error in missing prop on spinnerButton component

* [./components/spinner_button.tsx]:
- convert class component to functional component - fix lint errors in spinner button

* fix:[spinner_button]: fix lint errors

* - fix: [add_emoji.tsx]: add an id selector to the SpinnerButton to fix issue in unit test for this file.
- fix: [add_emoji.test.tsx]: find the saveButton with id selector instead of using element directly (was causing test fai)
- update test snapshots

* fix[add_emoji]: replaced id with data-testid to be used in unit test
